Perform these steps to configure the Internet Key Exchange (IKE) policy, beginning in global configuration mode: Creates an IKE policy that is used during IKE negotiation. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Sample route-target prefix and suffix. Additional documentation about EVPN Multi-Site architecture and related topics can be found at the sites listed here. Site-internal BUM replication can use multicast (PIM ASM) or ingress replication. Whatever is sent through the ingress point into the overlay network will leave at the respective egress point. Specifies which transform sets can be used with the crypto map entry. The route-target rewrite helps ensure that the ASN portion of the automated route target matches the destination autonomous system. access-switch1(config-if-range)# switchport access vlan 3 The capture buffer will store the packets to be captured. End-to-end VXLAN OAM is supported as of Cisco NX-OS 7.0(3)I7(1). In our case, this is Fast Ethernet0 and well capture both ingress and egress packets. As a subconfiguration of the BGW definition, a time-delayed restore operation for BGW virtual IP address advertisement can be set. In the BGW-on-spine model (Figure 15), the BGW is co-located with the spine of the site-internal network (fabric). The route targets must be enabled for the IPv4/IPv6 address family and specifically for EVPN. The next time you reboot the device, the current running configuration will be loaded from flash memory (as startup-config). Specifies the encryption algorithm used in the IKE policy.

Active virtual MAC address is 0000.0c07.ac01 The PIP address is responsible in the BGW for handling BUM traffic. All of the devices used in this document started with a cleared (default) configuration. The Cisco870 series routers support the creation of Virtual Private Networks (VPNs). Note: The use of a route server is optional, but it simplifies the EVPN Multi-Site deployment. [an error occurred while processing this directive], crypto isakmp client
Nevertheless, a single data center fabric also has scale limits, and thus the scale-out approach for a single large data center fabric exists. The Cisco 4000 Family Integrated Services Router (ISR) revolutionizes WAN communications in the enterprise branch. Define the BGP routing instance with a site-independent autonomous system. If a deployment consists of many sites and many BGWs, the need for full-mesh eBGP peerings between any BGWs for the overlay control plane may create additional complexity. During IKE negotiation, the peers agree to use a particular transform set for protecting data flow. Track object 10 state Up decrement 5 Copyright 2022 | Privacy Policy | Terms and Conditions | Hire Me | Contact | Amazon Disclaimer | Delivery Policy. Cisco routers and other broadband devices provide high-performance connections to the Internet, but many applications also require the security of VPN connections which perform a high level of authentication and which encrypt the data between two particular endpoints. The route targets must be enabled for the IPv4/IPv6 address family and specifically for EVPN. HSRP supports different types of tracking, such as interface tracking, routing table tracking, reachability tracking etc. Note: The hardware and software requirements for the site-internal BGP Route Reflector (RR) and VTEP of a VXLAN BGP EVPN site remain the same as those without the EVPN Multi-Site BGW. Sub-menu: /ip ipsec Package required: security Internet Protocol Security (IPsec) is a set of protocols defined by the Internet Engineering Task Force (IETF) to secure packet exchange over unprotected IP/IPv6 networks such as Internet. The neighbor configuration for the IPv4 unicast global address family (VRF default) facilitates shared-border underlay routing. Associate the Layer 2 VNI with the NVE interface (VTEP) and configure the relevant site-internal and site-external BUM replication modes (dual mode). ), with the addition of a classic Ethernet multihoming approach (vPC) to connect to the legacy network infrastructure (Figure 24). Some deployment scenarios use an additional spine tier (superspine), and other deployments have a routed Layer 3 cloud. Whereas the BGW-to-cloud approach considers the Layer 3 cloud to be extended across a long distance, the superspine likely exists within a physical data center. Cisco Secure Client (including AnyConnect) Deep visibility, context, and control. In this article, I will go over deploying a new Routing and Remote Access (RRAS) server and connecting it to an Azure Gateway.The process is not limited to home labs, but it could be also used for a small office environment where a Site-to-Site VPN to In addition to per-BGW or per-site external connectivity, connectivity can be provided through a shared border. Resources at the client site are unavailable to the central site. Cisco ASA Erase Configuration; Cisco ASA ASDM Configuration; Cisco ASA Security Levels; Unit 2: NAT / PAT. This ID is defined as part of the BGW configuration (evpn multisite border-gateway ). It is a very good security practice to lock-down all access lines of a switch with a password. The autonomous system portion of the route target will be rewritten with the ASN specified in the BGP peering configuration. The A-BGW allows the scaling of the BGWs horizontally in a scale-out model and without the fate sharing of interdevice dependencies. Chuck says. crypto isakmp policy 1 encr aes authentication pre-share group 2 ! Note: Cisco NX-OS follows the following implementation as defined by IETF RFC-7342, draft-ietf-bess-evpn-overlay, draft-ietf-bess-evpn-prefix-advertisement, and draft-ietf-bess-evpn-inter-subnet-forwarding. GRE over IPSEC VPN and OSPF dynamic routing protocol configuration included. access-switch1(config-if-range)# exit, access-switch1(config)# exit To monitor the status of our buffer, we can use the show monitor capture buffer command: 2. This document uses the virtual IP address to refer also to the EVPN Multi-Site anycast IP address. A VRF consists of an IP routing table, a derived Cisco Express Forwarding table, and guidelines and routing protocol parameters that control the Most commonly, an IGP is used to provide reachability between the intrasite VTEP (leaf), the spine, and the BGWs. The VRF member name must match the VRF context name in the next step. The site-internal underlay can be deployed in various forms. This scenario covers the case where the links connecting the primary router with ISP get down, so we assume the secondary router can reach the internet (it has different links). Thus, the local site-internal network can be configured with ingress replication while the remote site-internal network can be configured with a multicast-based underlay. Router# config terminal Router(config)# hostname London London(config)# ip domain-name mydomain.com ("Cisco ASA Firewall Fundamentals" and "Cisco VPN Configuration Guide") which are available at Amazon and on this website as well. IP SLA 1 reachability Alternatively, BGWs can be co-located on the spine of the fabric. Note: The VLAN ID has no significance for any endpoint-facing function. IETF specifications for EVPN Multi-Site architecture, draft-ietf-bess-evpn-prefix-advertisement, Interface-less IP-VRF-to-IP-VRF advertisement, draft-ietf-bess-evpn-inter-subnet-forwarding. Creates an IKE policy group containing attributes to be downloaded to the remote client. How to configure a Cisco Layer 3 Switch-InterVLAN Routing Without Router, Cisco Switch Port Security Configuration and Best Practices. Your email address will not be published. We Provide Technical Tutorials and Configuration Examples about TCP/IP Networks with focus on Cisco Products and Technologies. ROUTER1(config)# track 10 ip sla 1 reachability. The BGWs at the remote sites have site-internal VTEPs behind them. Easy VPN server-enabled devices allow remote routers to act as Easy VPN Remote nodes. The use of anycast IP addresses or virtual IP addresses provides network-based resiliency, instead of resiliency that relies on device hellos or similar state protocols. Lets take a look at some of the basic features offered by Embedded Packet Capture: Figure 1. Unlike the BGW, the shared border is completely independent of any VXLAN EVPN Multi-Site software or hardware requirements, it is sloley a border node topologically outside of a single or multiple Sites. For VPN resilience, the remote site should be configured with two GRE tunnels, one to the primary HQ VPN router, and the other to the backup HQ VPN router. Table 1. It thus offers the possibility of seamless extension between compartments and fabrics. I want to be able to create virtual machines in which my other laptops on the network can utilize. Thus, in the case of two BGWs, you need two prefixes in every BGW: one local to the BGW and one received remotely. The BGW is the binding device between the site-internal VTEPs and everything that is site external. I have a Cisco 3750 48 port and also have an HP Proliant server i want to connect to my switch. Router RTR-A RTR-A(config)# int fa0/1 RTR-A(config-if)# ip address 10.10.10.1 255.255.255.0! This document describes how to achieve a Virtual Extensible LAN (VXLAN) Ethernet Virtual Private Network (EVPN) Multi-Site design by integrating VXLAN EVPN fabrics with EVPN Multi-Site architecture for seamless Layer 2 and Layer 3 extension. In fact, as soon as the first router comes back, this last comes primary again (because it has the higher HSRP priority and the preempt is configured on both ones). Specifies the IPSec group and IPSec key value for the VPN connection. The important part of this output is not its detailed information, but the fact that one BGP EVPN route type 4 prefix must exist for each BGW at the local site. In my setup, i have two remote systems running on 172.16.0.10 on Side A and 192.168.10.20 on Side B; While the network design in the underlying topology was predominantly Layer 3 and an efficient hierarchy was present, with the introduction of the overlay network this hierarchy became hidden. The co-existence of these different first-hop gateway approaches is not supported today, and hence you need to achieve alignment between the legacy sites and VXLAN BGP EVPN sites. With the route server or remote BGW potentially multiple routing hops away, you must increase the BGP session Time-To-Live (TTL) setting to an appropriate value (ebgp-multihop). The anycast BGW (A-BGW) performs the BGW function as described in the previous section. On my sons bedroom I am going to wire his Notebook (DELL INSPIRON 1500) hes on 3rd grade and starting to use his computer quite a lot. Versatile, reliable, flexible and powerful, the Cisco switch product line (such as the 2960, 3560, 3650, 3850, 4500, 6500, 9400 series etc) offer unparalleled performance and features. Latest operation return code: Timeout Default route: External router versus BGW. The configuration of the BGP reachability function across multiple hops (ebgp-multihop) and preservation of the next hop between the BGWs are common settings. You get centralized and remote management capabilities through web-based tools and Cisco IOS Software for full visibility and control of network configurations at the remote site. interface Ethernet0/0 Similarly, the route target can be derived automatically by using the BGP autonomous system followed by the VNI defined as part of the VRF instance (ASN:VNI). HSRP: Fa4 Grp 1 Hello Received when interface down. After configuring the basic steps above, lets see some useful commands to monitor your configuration or troubleshoot possible problems: access-switch1# show run (Displays the current running configuration) Copyright 2022 | Privacy Policy | Terms and Conditions | Hire Me | Contact | Amazon Disclaimer | Delivery Policy. With EVPN Multi-Site interface tracking, the BGW function and advertisement and participation are controlled. The route distinguisher for the IP VRF instance can be derived automatically by using the router ID followed by the internal VRF ID (RID:VRF-ID). If the desired network services deployment can be achieved through routing and routing redundancy, EVPN Multi-Site architecture also supports these connectivity models. Cisco 4000 Family Integrated Services Routers (ISRs) form an Software Defined WAN platform that delivers the performance, security, and convergence capabilities that todays branch offices need.. The topology that works best depends on the use case. Note: The ip pim sparse-mode setting is needed only for intrasite multicast-based BUM replication. Priority 101 (configured 101) My ISP will be inside my offices room. There are two types of Capture Buffers: Linear and Circular. Specify the OSPF network type (point to point) and OSPF process tag for site-internal underlay routing. enable HSRP group 1 and set the virtual address to 10.10.10.3 Multisite bgw-if oper down reason: DCI isolated. In this case, for example, route-target 65501:50000 at the local site can be rewritten as 65036:50000 on the route server and then as 65520:50000 at the remote site. It is specifically not necessary to influence the availability of the EVPN Multi-Site virtual IP address, because if the shared border becomes absent, no external routes can be advertised to the site-internal network. On a Layer3-capable switch, the port interfaces work as Layer 2 access ports by default, but you can also configure them as Routed The Cisco Easy VPN client feature can be configured in one of two modesclient mode or network extension mode. With the implementation of this function, every IETF RFC and draft conforming VTEP can peer with a BGW either site internal or site external without specifically needing to have EVPN Multi-Site BGW capabilities. With new levels of This approach avoids polarization, given the entropy of VXLAN, and it increases resiliency. Note: External learned IP prefixes can be redistributed to BGP EVPN from any BGP IPv4/IPv6 unicast, Open Shortest Path First (OSPF), or other static or dynamic routing protocol that allows redistribution to BGP EVPN. access-switch1(config)#, STEP6: Assign IP address to the switch for management, !Management IP is assigned to Vlan 1 by default EVPN Multi-Site technology is based on IETF draft-sharma-multi-site-evpn. In the case of EVPN Multi-Site architecture, a site-internal MAC address or IP prefix advertisement originates from the local BGWs with their anycast VTEPs as the next hop. Virtual IP address is 1.1.1.3 The isolated BGW withdraws all of its advertised BGP EVPN routes (Route Type 2, Route Type 3, Route Type 4, and Route Type 5). End-of-Life Announcement for the Cisco AnyConnect VPN Client 2.5 (for Desktop) EOL/EOS for the Cisco AnyConnect VPN Client 2.3 and Earlier (All Versions) and 2.4 (for Desktop) EOL/EOS for the Cisco Secure Desktop 3.4.x and Earlier ; UPDATED: 2020 Cisco Catalyst switches equipped with the Enhanced Multilayer Image (EMI) can work as Layer 3 devices with full routing capabilities.For example, some switch models that support layer 3 routing are the 3550, 3750, 3560 etc. Unlike serial connections the Ethernet WAN interface could be in an up/up condition and in fact be down. Please have a look at HSRP Scenario 2 with track objects and IP SLA configuration. Note: This route map is an extension of the one previously created for the default route filtering. Installing Security Device Manager (SDM) on a Cisco Rou Disabling Cisco Router Password Recovery Service, How To Configure DNS Server On A Cisco Router, Configuring PPTP (VPDN) Server On A Cisco Router. RTR-B(config-if)# standby 1 priority 100, ! Depending on the VRF awareness and number of VRF instances, this option can be acceptable, but the configuration complexity will increase with the number of VRF instances. Nevertheless, this document provides best practices and recommendations for a successful deployment. Finally, we've also included a number of useful Embedded Packet Capture troubleshooting commands to monitor the status of the capture points and memory buffer. There are two tunneling modes available for MX-Z devices configured as a Spoke:. For resiliency, a pair of route servers is recommended. Cisco Secure Client (including AnyConnect) Deep visibility, context, and control. Monitor, manage and secure devices Continuously monitor all file behavior to uncover stealthy attacks. Define the Layer 3 VNI and attach it to a BGW local VLAN. Cisco routers and other broadband devices provide high-performance connections to the Internet, but many applications also require the security of VPN connections which perform a high level of authentication and which encrypt the data between two particular endpoints. access-switch1# show mac address-table (Displays current MAC address table and which MAC address is learned on each interface). Importing packets into a Network Analyzer. Although it is much better to configure an external AAA server (for centralized Authentication Authorization and Accounting), in this article we will just configure a password on each access line (VTY lines for Telnet and Console line): access-switch1(config)# line vty 0 15 ipsec-isakmp dynamic dynmap, crypto ipsec client
ip prefix-list HOST-ROUTE seq 5 permit 0.0.0.0/0 eq 32. Prevent breaches. The only specific requirements for the Layer 3 cloud are that it provide IP connectivity between the virtual IP and PIP addresses of the BGWs and accommodate the MTU for the VXLAN-encapsulated traffic across the cloud. Capture points need to define the following: EPC configuration is an easy 5 step configuration process. The IR829 brings together enterprise-grade wireline-like services such as Quality of Service (QoS), Cisco advanced VPN technologies (DMVPN and Flex VPN) and multi-VRF for WAN, highly secure data, voice, and video communications and Cisco IOx, an open, extensible environment for hosting applications at the network edge. In this article, I will go over deploying a new Routing and Remote Access (RRAS) server and connecting it to an Azure Gateway.The process is not limited to home labs, but it could be also used for a small office environment where a Site-to-Site VPN to First lets enable HSRP on the WAN interface with Virtual IP 1.1.1.3. It also introduces split-horizon rules to help ensure that traffic entering the BGW from one flood domain does not return to the same flood domain. Note: BGP EVPN allows BUM replication based on either ingress replication or multicast (PIM ASM). Lets see how to configure SSH access to a Cisco device. For details, see the Cisco IOS Security Configuration Guide and Cisco IOS Security Command Reference. Network services integration is a big topic, especially when multiple sites are present and you need to distribute firewalls and load balancers across them. In this article. Configure the neighbor with the EVPN address family (L2VPN EVPN) for the site-external overlay control plane facing the BGW. ip local pool {default | poolname} [low-ip-address [high-ip-address]]. For BUM replication, either multicast (PIM ASM) or ingress replication can be used. Lab. Group name is hsrp-Et0/1-1 (default), Track 10 With the default configurations, the router provides secure connectivity by encrypting the traffic sent between remote sites. Specifies a local address pool for the group. To use multiple VRF instances on a single physical Layer 3 interface, the use of subinterfaces is recommended. Enable feature nv overlay for the VXLAN VTEP capability. External connectivity includes the connection of the data center to the rest of the network: to the Internet, the WAN, or the campus. Any VPN connection requires both endpoints be configured properly to function. Yes, Im the writer of the book you see here (Cisco ASA Firewall Fundamentals). The configuration presented here shows the site-external underlay and overlay configuration on a BGW. In addition to verification of the state, control-plane protocol actions are performed as described in the Failure scenarios section. Explore Catalyst Wireless Gateway Industrial . This document focuses on EVPN Multi-Site architecture, so the site-internal overlay configuration for dual- and multiple-autonomous-system designs is omitted. Also, the services that a leaf requires are reachable through one hop at the BGW and spine. In this article we will discuss two different network scenarios where HSRP can be used to provide redundancy between two paths from an internal LAN network towards the outside world (WAN or Internet). Define the loopback1 interface as the NVE source interface (PIPVTEP). Creates a dynamic crypto map entry and enters crypto map configuration mode. RTR-A(config-if)# ip address 10.10.10.1 255.255.255.0, ! Explore Catalyst Wireless Gateway Industrial . A more elegant approach to a scale-out EVPN Multi-Site environment is to use a star point to broker the site-external overlay control plane (Figure 19). Unlike other lower class switch vendors (which are plug-and-play), the Cisco switch needs some initial basic configuration in order to enable management, security and some other important features. Cisco 2900 Series Integrated Services Router (ISR) that runs Cisco IOS software version 15.3(3)M1; The information in this document was created from the devices in a specific lab environment. Written by Administrator. The configuration for a site-external route server is shown here. Enter your Email below to Download our Free Cisco Commands Cheat Sheets for Routers, Switches and ASA Firewalls. username name {nopassword | password password | password encryption-type encrypted-password}. In addition to physical-connectivity issues, you need to consider scenarios such as link failure, designated-forwarder reelection, and BUM-traffic forwarding (especially in a failure scenario). For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. New-York router configuration. In addition to preventing the VXLAN BGP EVPN fabric from becoming a transit network, you can introduce use another optimization through route filtering. Note: Selective advertisement is defined by the configuration of the per-tenant information on the BGW. Note: Site-external EVPN peering is always considered to use eBGP with the next hop the shared border. The remaining BGWs withdraw all BGP EVPN Route Type 4 (Ethernet segment) routes received from the now isolated BGW because reachability is missing. Test the Site-to-Site connections. Can you post the relevant configuration to check it out? The easy interconnection of these compartments is achieved through the integrated Layer 2 and Layer 3 extension provided by EVPN Multi-Site architecture. With EVPN Multi-Site architecture, two placement locations can be considered for the BGW. As of Cisco NX-OS 7.0(3)I7(1) for the Cisco Nexus 9000 Series EX- and FX-platform switches, the classification and rate limiting are applied globally to each BGW. The VRF-lite coexistence model (Figure 20) uses the traditional approach to providing external connectivity to a VXLAN BGP EVPN fabric. As shown, the first 2 translations directed to 74.200.84.4 & 195.170.0.1 are DNS requests from internal host 192.168.0.6.The third entry seems to be an http request to a web server with IP address 64.233.189.99.. The Layer 3 cloud can be any routed service, such as a flat Layer 3 routed network, a Multiprotocol Label Switching (MPLS) Layer 3 VPN (L3VPN), or other provider services. ROUTER2(config-if)# no shut I am working on a specific situation and in a lab if I shut down the switch port connecting R2 and turn it back on. In my kitchen we have an Alexa and a small Notebook for music and recipes. That is, a BGW at the source site doesnt require a neighboring BGW at the destination site; a traditional VTEP will suffice. Hello time 3 sec, hold time 10 sec Enable the IPv4 unicast address family for this peering. Therefore, all traffic originating from remote sites and destined for the virtual IP address is rerouted to the remaining BGWs that still host the virtual IP address and have it active. Note: In the shared-border deployment, the BGW of every site must have connectivity to the shared border. Full set of commands and diagrams included. Cisco ASA Erase Configuration; Cisco ASA ASDM Configuration; Cisco ASA Security Levels; Unit 2: NAT / PAT. access-switch1(config-std-nacl)# exit, !Apply the access list to Telnet VTY Lines Tunneling. Applying the crypto map to the physical interface instructs the router to evaluate all the traffic against the security associations database. Point-to-point IP addressing is used for site-external underlay routing (point-to-point IP addressing with /30 is shown here). Next hello sent in 0.208 secs All the Layer 2 configuration settings are provided solely to help ensure VXLAN traffic termination and reencapsulation for transit through the BGW only. You will get the initial command prompt Switch>, Type enable and hit enter. Sorry about that. This article shows how to configure, setup and verify site-to-site Crypto IPSec VPN tunnel between Cisco routers. The use of EVPN doesnt preclude the use of a network-based BUM replication mechanism such as multicast. EVPN Multi-Site architecture has many different deployment scenarios that apply to different use cases. Cisco ASA Site-to-Site IKEv1 IPsec VPN; Cisco ASA Site-to-Site IKEv1 IPsec VPN Dynamic Peer; 90.81.3.157 => ISP router Your email address will not be published.

Now that the tunnel has been established and firewall rules in place, you can try to check whether the connection has been established between the local sites that are set to communicate via the IPSec VPN tunnel. Track object 10 state Down decrement 5 Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. configuration address respond, aaa authentication login
With seamless and controlled Layer 2 and Layer 3 extension through the use of VXLAN BGP EVPN within and between sites, the capabilities of VXLAN BGP EVPN itself have been increased. Creates source proxy information for the crypto map entry. As a result of this trend, network state explosion for MAC and ARP entries presented itself. Switch(config)#. access-switch1(config-vlan)# exit, ! Note: The redistribution from the locally defined interfaces (direct) into BGP is performed through route-map classification. Next hello sent in 1.184 secs Additional considerations apply to first-hop gateway use and placement. The virtual IP address is represented by a dedicated loopback interface associated with the Network Virtualization Endpoint (NVE) interface (multisite border-gateway interface loopback100). As an Amazon Associate I earn from qualifying purchases. In this scenario, the BGW is connected to the site-internal VTEPs (usually through spine nodes) and to a site-external transport network that allows traffic to reach the BGWs at other, remote sites. With the route reflector already present in the fabric, and with all VTEPs, including the BGW, peering with it, the exchange of designated-forwarder election messages is achieved (Figure 7). access-switch1(config-vlan)# name STUDENTS This is accomplished with the use of access control lists. With selective control-plane advertisement and the enforcement of BUM traffic at the BGWs, you can achieve more control over extension between fabrics. With stretched IP subnets across multiple sites, the explicit location of a subnet becomes unclear, and more granular information must be provided in the routing tables. In addition to the site ID, the use the same Layer 2 VNI is needed to elect the designated forwarder from among the eligible BGWs. In our network above we will configure HSRP on both the LAN and the WAN interfaces of the two Routers. Once the import process is complete, our captured packets are displayed and we can analyse them in a more user-friendly environment: Figure 4. This approach requires the BGW to locally originate the default route and inject it into the BGP EVPN control plane facing the site-internal VTEPs. See the Cisco IOS Security Command Reference for detail about the valid transforms and combinations. R2 is not becoming part of that standby 1 group. ROUTER2(config-if)# standby 1 preempt, ROUTER2(config)# ip route 0.0.0.0 0.0.0.0 1.1.1.100 <- Default Gateway route to ISP. Subsequent releases will expand this capability to enable asymmetric VNI assignment, in which different VNIs can be stitched together at the BGW level. Yes you are right. With EVPN Multi-Site architecture and the BGWs, you can compartmentalize functional building blocks within the data center. This interface connects to the external router. In this lab, a small branch office will be securely connected to the enterprise campus over the internet using a broadband DSL connection to demonstrate ASA 5505 site-to-site VPN capabilities. RTR-A(config-if)# standby 1 ip 10.10.10.3, ! The back-to-back connectivity model (Figure 11) provides an alternative to the topology in which the BGWs are connected to a Layer 3 cloud. Configure the neighbor in the IPv4 unicast global address family (VRF default) to peer with the site-external loopback interface (loopback0) of the BGW. VXLAN EVPN Multi-Site architecture is a design for VXLAN BGP EVPNbased overlay networks. The designated-forwarder election status can be viewed per BGW and per VLAN and L2VNI. Figure6-1 shows a typical deployment scenario. access-switch1# show vlan (Displays all vlan numbers, names, ports associated with each vlan etc) VXLAN EVPN Multi-Site architecture simplifies legacy site integration and consistently provides the required Layer 2 and Layer 3 extension. A transform set represents a certain combination of security protocols and algorithms. Perform these steps to apply a crypto map to an interface, beginning in global configuration mode: Enters the interface configuration mode for the interface to which you want the crypto map applied. The configuration to enable Layer 3 extension through an EVPN Multi-Site BGW closely follows the configuration for a normal VTEP. Test the Site-to-Site connections. what is the defferent between wr used to save configuration and copy run start, thanks i liked the configurations used. Also enters the Internet Security Association Key and Management Protocol (ISAKMP) group policy configuration mode. The article is updated now. It is important to note that more than one router must be employed at HQ to provide resiliency. This approach allows the environment to scale well from control-plane peering, and it also eases the management burden of configuration and operation. You can apply storm control on the VPC BGW Ethernet interfaces connecting to the site-internal switches. The OpenVPN community project team is proud to release OpenVPN 2.5.2. Site-to-Site connections can be used to create a hybrid solution, or whenever you want secure connections between your on-premises networks and your virtual networks. Ensure the loopback interfaces IP address is redistributed into BGP EVPN, specially towards Site-External. You could also use a RADIUS server for this. In BGP EVPNbased overlay networks, the control plane defines what the data plane and VXLAN use to build adjacencies, for example. The settings for Router 2 are identical, with the only difference being the peer IP Addresses and access lists: Similar to the process in the shared-border scenario, the integration of a legacy site is achieved by positioning a set of VTEPs external to the VXLAN BGP EVPN sites (a pair of vPC BGWs). A BGP route server performs the same route reflection function as an iBGP route reflector. The underlay must be reachable between the BGW and the shared border: specifically between the loopback interfaces that provide the VTEP and the overlay peering function. Comments. Priority 101 (configured 101) The Layer 2 VNI chosen refers to the vn-segment ID chosen in the previous step. These are the steps for the FortiGate firewall. A permutation of this topology is a square with an additional cross between the BGWs, which is slightly more resilient and does not require designated-forwarder reelection if a single link fails. To participate in the designated-forwarder election, the configuration of the same site ID is required. You can configure the 10.20.20.x network to work as hsrp on the routers, so the server will see the HSRP VIP address as default gateway. I will be using streaming from Netflix on my family room. rtr-remote local, aaa authorization network
The documentation set for this product strives to use bias-free language. You can use point-to-point IP addressing or IP unnumbered addressing (IP unnumbered support started in 7.0(3)I7(2)) for site-internal underlay routing (point-to-point IP addressing with /30 is shown here). 7 state changes, last state change 00:06:08 Two types of VPNs are supportedsite-to-site and remote access. When you define the site-external BGP peering session (peer-type fabric external), rewrite and reorigination are enabled. Note The Cisco Easy VPN client feature supports configuration of only one destination peer. Cisco 5512-X Series ASA that runs software Version 9.4(1) Cisco 1941 Series Integrated Services Router (ISR) that runs Cisco IOS software Version 15.4(3)M2; The information in this document was created from the devices in a specific lab environment. ROUTER1(config)# ip route 0.0.0.0 0.0.0.0 1.1.1.100 <-Default Gateway route to ISP. For additional information about the E-E-E deployment model and why I-E-I is the recommended approach, see the For more information section at the end of this document. It is important to note that more than one router must be employed at HQ to provide resiliency. Note: The route server is not a VTEP or BGW and hence should not have the next hop pointing to itself. I dont like graphical GUI or web management at all, so I will show you command line configuration (CLI) which is much more powerful and actually forces the administrators to learn what they are doing on the device. As a result of these actions, the BGW will be isolated from a VTEP perspective in both the site-internal and site-external networks (Figure 8). HSRP Ethernet0/1 1, ROUTER1#show standby Only IP addresses in VRF default that are extended with the matching tag of the route map are redistributed. Active router is 1.1.1.2, priority 100 (expires in 10.848 sec) Sub-menu: /ip ipsec Package required: security Internet Protocol Security (IPsec) is a set of protocols defined by the Internet Engineering Task Force (IETF) to secure packet exchange over unprotected IP/IPv6 networks such as Internet. I hate WI-FI they get slow, it drops signal from time to time. For EVPN Multi-Site architecture, BGP EVPN Route Type 4 is used to perform designated-forwarder election. Because of the importance of the BGW, you need to consider not only scale and resiliency, but also the behavior during a failure situation. Note: As of Cisco NX-OS 7.0(3)I7(1) for the Cisco Nexus 9000 Series EX- and FX-platform switches, local endpoint connectivity is not supported on an EVPN Multi-Site BGW. The Cisco 870 series routers support the creation of Virtual Private Networks (VPNs). This example uses a local authentication database. The VXLAN Border Gateway Protocol (BGP) EVPN fabric (or site) can be extended at Layer 2 and Layer 3 with various technologies. In addition to using route peering to the external router through eBGP, you may sometimes want to advertise the default route to the fabric. Note: Without the route filter, the VXLAN BGP EVPN fabric can accidentally become a transit network for traffic external to the fabric. This example implements a username of Cisco with an encrypted password of Cisco. access-switch1(config)# line vty 0 15 HSRP Ethernet0/0 1 Note The material in this chapter does not apply to Cisco850 series routers. security-association lifetime seconds 86400, crypto map static-map 1
More generally, SVIs cannot currently be defined on the BGW. If that single default gateway fails, then communication outside the LAN is not possible. The FortiGate firewall in my lab is a FortiWiFi 90D (v5.2.2), the Cisco router an 2811 with software version 12.4(24)T8.. The example in this chapter illustrates the configuration of a remote access VPN that uses the Cisco Easy VPN and an IPSec tunnel to configure and secure the connection between the remote client and the corporate network. Specifies the peer IP address or hostname for the VPN connection. The route target is defined based on the export configuration of the VRF instance in which the prefix was learned. Note: Site-external EVPN peering is always considered to use eBGP with the next hop the BGW. The model in which the BGWs are placed between the spine and superspine (Figure 14) is similar to the BGW-to-cloud scenario. crypto isakmp policy 1 encr aes authentication pre-share group 2 ! Configuring Internet Key Exchange Version 2 (IKEv2) and FlexVPN Site-to-Site . At this point, we have completed the IPSec VPN configuration on the Site 1 router. This article introduced the Cisco Embedded Packet Capture feature offered on all Cisco router IOS platforms from version 12.4.20T and above. However the above scenario is for illustrating the configuration details of HSRP. Please provide me the name of your book which also has these. It assumes that the individual data center fabrics (site-internal networks) are already configured and up and running. Ensure the loopback interfaces IP address is redistributed into BGP EVPN, specially towards Site-External. Note: Our access list includes traffic originating from both hosts because we want to capture bidirectional traffic. The percentage can be adjusted from 0% (block all classified traffic) to 100% (allow all classified traffic). Adjust the MTU value of the interface to accommodate your environment (the minimum value is1500 bytes plus VXLAN encapsulation). Define a route map that matches the prefix list, and prevent that match from being advertised to the external connectivity. Continuously monitor all file behavior to uncover stealthy attacks. By default, all physical ports of the switch belong to the native VLAN1. In a square topology, in which the designated forwarder at the local site is connected to the nondesignated-forwarder spine at the remote site, BUM traffic cannot be forwarded to the remote site without the link between the BGW at the same site (Figure 12). Latest operation return code: OK Configuring Certificate Enrollment for a PKI. access-switch1(config-if-range)#switchport mode access To allow the site-internal configuration to use the automated route target and require no change to any VTEP, the rewriting of the autonomous system portion on the route target must be possible, because the export route target at the local site must match the import route target at the remote site. A dynamic crypto map policy processes negotiation requests for new security associations from remote IPSec peers, even if the router does not know all the crypto map parameters (for example, IP address). The simplest configuration is to leave all ports in the default Vlan 1 (i.e do not create any VLANs on the switch) and just connect your modem and Access Points to the switch. First configure the tracking mechanism on the active router. Enable feature nv overlay for VXLAN VTEP capability. RTR-A(config-if)# standby 1 priority 110, ! The FortiGate firewall in my lab is a FortiWiFi 90D (v5.2.2), the Cisco router an 2811 with software version 12.4(24)T8.. Migrating ASA to Firepower Threat Defense Site-to-Site VPN Using IKEv2 with Certificates AnyConnect HostScan Migration 4.3.x to 4.6.x and Later 29-Aug-2019 Cisco ASA REST API Quick Start Guide 05-Jun-2019 This section explores the configurations needed for the VNIs, for either Layer 2 or Layer 3 extension. Enable feature ospf for underlay IPv4 unicast routing. BGW back-to-back model (BUM traffic acceptable). The route-target rewrite helps ensure that the ASN portion of the automated route target matches the destination autonomous system. Microsoft Azure Route Based VPN to Cisco ASA. These are the steps for the FortiGate firewall. Although this approach doesnt create any problems from a traffic volume or a resiliency perspective, the use of a control-plane exchange between the BGW traversing the leaf node is not natural. State is Standby In addition to the designated-forwarder election status, you can display the specific designated-forwarder election messages. For details, see the Cisco IOS Security Configuration Guide and Cisco IOS Security Command Reference. Using HSRP, the two routers will have a physical IP address configured on their LAN-facing interface, but they will have also a Virtual (HSRP address) which will be used as the default gateway address for hosts on the LAN. VXLAN BGP EVPN provides optimal egress route optimization using the distributed IP anycast gateway function at every VTEP. Define a Layer 3 interface to enable the previously defined VNI to become a fully functional Layer 3 VNI. The route-target rewrite function is performed on the EVPN Multi-Site BGW facing the site-external overlay peering. The underlay transport network within or between the sites is responsible for hashing the VXLAN traffic among the available equal-cost paths. access-switch1(config-if-range)# shutdown These came first, essentially they work like this, If traffic is destined for remote network (x) then send the traffic encrypted to local security gateway (y). Note: Where Local Security Gateway is a firewall at YOUR site, NOT in Azure! The scale-out approach offers an improvement for data center fabrics. The network above can be implemented in a single building/data center, but can also be implemented in two separate buildings/data centers. During this configuration phase, we need to provide a name for the capture point, we selected CPpoint-FE0 to make it easy to distinguish. To examine the buffers contents, use the 'show monitor capture buffer dump' command: 86621680: 5475D061 2856F4CE 469A161C TuPa(VtNF86621690: 08004500 00347440 40007F06 57B7C0A8 ..E..4t@@W7@(866216A0: 0302D056 9BCBC6BC 00506100 C18E0000 ..PV.KF<.Pa.A866216B0: 00008002 20003676 00000204 04EC0103 . .6v..l..866216C0: 03020101 040200 . 15:04:51.015 UTC May 25 2015 : IPv4 LES CEF : Fa1 Fa0. Local virtual MAC address is 0000.0c07.ac01 (v1 default) Because BGP is already in use for EVPN and EVPN Multi-Site architecture, it is the recommended option for exchanging routing information with external routers (VRF-lite external connectivity with the use of a subinterface). access-switch1(config)#, STEP7: Assign default gateway to the switch, access-switch1(config)# ip default-gateway 10.1.1.254, STEP8: Disable unneeded ports on the switch, ! ROUTER2(config-if)# ip address 192.168.1.2 255.255.255.0 Note: The switch will not ask you for a password when entering into Privileged EXEC mode (i.e after typing enable) if it has the default factory configuration. Complete these steps in order to set up the site-to-site VPN tunnel via the ASDM wizard: Open the ASDM and navigate to Wizards > VPN Wizards > Site-to-site VPN Wizard: Click Next once you reach the wizard home page: Note: The most recent ASDM versions provide a link to a video that explains this configuration. However, for eBGP networks, a function similar to the route-reflector function is offered by the route server, as described in IETF RFC 7947: Internet Exchange BGP Route Server. ROUTER2(config-if)# no shut This section presents technical information about the main components of the EVPN Multi-Site architecture and describes failure scenarios. For more information on the use of vPC BGWs to integrate legacy networks with VXLAN EVPN fabrics, including a detailed description of the supported use cases and configuration exmaples, please refer to the NextGen DCI with VXLAN EVPN Multi-Site Using vPC Border Gateways White Paper available in the For more information section at the end of this document. ROUTER2(config-if)# standby 1 ip 192.168.1.3 As long as one of these interfaces is operational and available, the BGW can extend Layer 2 and Layer 3 traffic to remote sites. Product overview. Product overview. Note: If BGP EVPN control-plane communication between BGWs traverses a site-internal BGP route reflector, the route reflector must support BGP EVPN Route Type 4. The advertisements to participate in designated-forwarder election are removed from the DCI-isolated BGW (Figure 9). The site-external or DCI interfaces commonly are connected to the network between sites, at which more BGWs are present. For the site-internal VTEP or leaf-to-leaf communication, the traffic pattern is through the BGW and spine combination. Note: The redistribution from the locally defined interfaces (direct) to BGP is performed through route-map classification. Active router is local It is a transport network that allows reachability between all the EVPN Multi-Site BGWs and external VTEPs. If this approach is deemed not beneficial, you can filter external connectivity routes between EVPN Multi-Site fabrics. rtr-remote local, crypto ipsec transform-set
The configuration for a BGW with a site-internal iBGP overlay is shown here. This means that if a destination IP stops responding to ICMP requests, then HSRP will trigger a failover condition and the standby router will take over and start passing traffic. With all the BGWs of the various sites connected to the superspine, you achieve a topology with the same network layers as in the BGW-to-cloud model. Note: The default route can also be received through a dynamic routing protocol. If a single EVPN Multi-Site instance loses external connectivity, but other sites still have external connectivity, EVPN Multi-Site Layer 2 and Layer 3 extension will be used to reach external connectivity for remote sites. The OpenVPN community project team is proud to release OpenVPN 2.5.2. This section contains basic steps to configure a GRE tunnel and includes the following tasks: An example showing the results of these configuration tasks is provided in the "Configuration Example" section. It defines the VPN membership of a customer site attached to the network access server (NAS). eBGP neighbor configuration is performed by specifying the source interface to loopback0. Because this route is originated locally or learned remotely, it will become an EVPN Route Type 5 route for the site-internal VTEPs. This action allows, for example, route-target 65501:50000 at the local site to be rewritten as 65520:50000 upon receipt of the BGP advertisements at the BGW of the remote site. Cisco 5512-X Series ASA that runs software Version 9.4(1) Cisco 1941 Series Integrated Services Router (ISR) that runs Cisco IOS software Version 15.4(3)M2; The information in this document was created from the devices in a specific lab environment. If it is too much can one of you point me a good equipment to buy for a home network? Packet Tracer 7.2.1 also features the newest Cisco ASA 5506-X firewall. On the data plane, designated-forwarder election and split-horizon rules complement the control-plane loop-prevention functions. The documentation set for this product strives to use bias-free language. Tunneling. If you have not performed these configurations tasks, see Chapter1 "Basic Router Configuration," Chapter3 "Configuring PPP over Ethernet with NAT," Chapter4 "Configuring PPP over ATM with NAT," and Chapter5 "Configuring a LAN with DHCP and VLANs" as appropriate for your router. The following configuration example shows a portion of the configuration file for the VPN and IPSec tunnel described in this chapter. You can configure a delay for the preempt to be sure your L2 network is stable before the HSRP changes. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. In this lab, a small branch office will be securely connected to the enterprise campus over the internet using a broadband DSL connection to demonstrate ASA 5505 site-to-site VPN capabilities. Configuring Internet Key Exchange Version 2 (IKEv2) and FlexVPN Site-to-Site . This flattening has both benefits and drawbacks. EVPN Multi-Site architecture requires every BGW from a local site to peer with every BGW at remote sites. Configure the neighbor with the EVPN address family (L2VPN EVPN) for the site-external overlay control plane facing the route server or remote BGW (peering to a pair of route servers is shown here). Alternative approaches for underlay reachability include the use of IGP, but this document focuses solely on eBGP. Split tunnel (no default route): Send only site-to-site traffic, meaning that if a subnet is at a remote site, the traffic destined for that subnet is sent over the VPN.However, if traffic is destined for a network that is not in the VPN mesh (for example, traffic going to a public web Dynamically generates and Multiprotocol-BGP (MP-BGP) peering with VPN address families is supported only as part of the default VRF instance. Versatile, reliable, flexible and powerful, the Cisco switch product line (such as the 2960, 3560, 3650, 3850, 4500, 6500, 9400 series etc) offer unparalleled performance and features. HSRP (Hot Standby Router Protocol) is the Cisco proprietary protocol for providing redundancy in router networks. Attach the route filter to the external connectivity peering facing the external router. Table 1 provides the hardware and software requirements for the Cisco Nexus 9000 Series Switches that provide the EVPN Multi-Site BGW function. They are present to reflect routes that are being sent from their clients that dont require a full mesh anymore. ROUTER2(config-if)# standby 1 preempt, ROUTER2(config)# interface ethernet 0/1 If the route reflector doesnt support BGP EVPN Route Type 4, direct BGW-to-BGW full-mesh iBGP peering must be configured.

BGW back-to-back model (BUM traffic not acceptable). Define a VRF context (IP VRF) with the appropriate instance name. If ip cef is not enabled, a message like the one below will appear, in which case you need to enable ip cef and re-enter the command. Note: Captured buffer can be exported to a number of locations including: flash: (on router), ftp, tftp, http, https, scp (secure copy) and more. This section lists the configurations used in this document. The configured rate-limiting level represents the amount of BUM traffic allowed from each interface that faces the site-external network. Note: Ingress replication to handle BUM replication between sites (site-external network) doesnt limit the use of the available BUM replication mode to a given site (site-internal network). Do it all fast and automatically. This section lists the configurations used in this document. Learn more about how Cisco is using Inclusive Language. This is specifically the case for the EVPN Multi-Site Layer 2 extension. The shared border acts as a common external connectivity point for multiple VXLAN BGP EVPN fabrics that are interconnected with EVPN Multi-Site architecture. In the shared-border model, additional ingress route optimization can be applied depending on the platform used. Now lets configure IP addresses and HSRP on the routers. With the BGWs between the spine and superspine, data center fabrics are scaled by interconnecting them in a hierarchical fashion. In this case, a dedicated set of border nodes are placed at the site-external portion of multiple sites. When choosing between shared and dedicated external connectivity interfaces, note that you also need to consider your needs for bandwidth and additional resiliency. Since The two routers have the same ISP default gateway which is 1.1.1.100, this means that if the track object is down in the active router, automatically the backup router cannot reach the internet either, is this configuration still possible if the ISP provides us with two links with different IP blocks? Define the BGP routing instance with a shared-border-specific autonomous system. Another important aspect of the configuration that well implement is reachability tracking. Our filter is now in place and we are ready for the next step. Also, you allow me to send you informational and marketing emails from time-to-time. BGP EVPN Route Type 4 is used for EVPN Multi-Site designated-forwarder election. First create the Layer2 VLANs on the switch, access-switch1(config)# vlan 2 document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. However, although DCI can be used to interconnect multiple data centers, within the data center large fabrics have become common to facilitate borderless endpoint placement and endpoint mobility. Preemption enabled In this lab, a small branch office will be securely connected to the enterprise campus over the internet using a broadband DSL connection to demonstrate ASA 5505 site-to-site VPN capabilities. Lab. But thats all about it. Note: IPv6 host-route filtering can be achieved in a similar way. access-switch1(config-line)# password strongtelnetpass Book Title. From an intersite underlay, eBGP can be replaced with any routing protocol, as long as a clean separation exists between the site-internal and site-external routing domains. Therefore, the BGW doesnt require a neighboring device to perform this function. The following configuration example focuses on the second method, using a static route to the external router. Set Up VPN between Cisco ASR 100 Series and Google Cloud Platform. Now if I either reboot it or clear the arp on R2 it starts to work. Lab. thank you so much. Detect, block, and remediate advanced malware across endpoints. My books do not cover the specific content you mention unfortunately. Note: Configure only one site-internal BUM replication mode: either multicast (PIM ASM) or ingress replication. A BGP route server is basically an eBGP route reflector, which in BGP terminology doesnt exist. IPsec protocol suite can be divided in following groups: Internet Key Exchange (IKE) protocols. Ron, yes the tutorial will apply to your case as well. It can also work if there are two IP blocks as you say, Two ASR 920 same BDI and DHCP configuration, how to configure HSRP. The underlay between the BGW and the shared border must be reachable, specifically between the loopback interfaces that provide the VTEP and the overlay peering function. The EVPN Multi-Site fabric-tracking function detects whether one or all of the site-internal interfaces are available. This version is the minimum software release required for EVPN Multi-Site architecture. The good news is, that you can build a Site-to-Site VPN to Azure without having to purchase a VPN appliance. We Provide Technical Tutorials and Configuration Examples about TCP/IP Networks with focus on Cisco Products and Technologies. Group name is hsrp-Et0/0-1 (default), Ethernet0/1 Group 1 From the point of view of the site-external network, no specific requirements are demanded apart from IP transport reachability between the BGWs and accommodation of an increased Maximum Transmission Unit (MTU) packet size. Similarly, the BGWs of the local site receive a MAC address or IP prefix advertised from remote BGWs with their anycast VTEPs as the next hop. As of Cisco NX-OS 7.0(3)I7(1), all connectivity to the BGW must be implemented through a Layer 3 physical interface or subinterface. This approach enables successful export and import route-target matching by using automated route-target derivation with route-target rewrite. The two switches on the LAN side and the two switches on the WAN side will provide the required L2 connectivity for HSRP to run on both the LAN and WAN connections. Table 2. With new levels of Lets create two new vlans (VLAN2 and VLAN3) and assign two ports to each one. It fixes two related security vulnerabilities (CVE-2020-15078) which under very specific circumstances allow tricking a server using delayed authentication (plugin or management) into returning a PUSH_REPLY before the AUTH_FAILED message, which can possibly be used to RTR-B(config-if)# standby 1 track fa0/0. As an Amazon Associate I earn from qualifying purchases. The site-external interfaces offer a configuration similar to that for the site-internal interfaces to understand their locations and the need for tracking (evpn multisite dci-tracking). Capture point is a traffic transit point where a packet is captured. RTR-A(config)# int fa0/1 Therefore, the standby router will become active. Note: Feature enablement and VXLAN, BGP EVPN, and EVPN Multi-Site global configuration have already been described in the BGW: Site-internal iBGP overlay. match ip address prefix-list DEFAULT-ROUTE. Now configure a default gateway address of 10.10.10.3 for your LAN hosts. For external connectivity, the use of physical Layer 3 interfaces is preferred, with each interface in a separate VRF instance. A dedicated set of BGWs can be placed at the leaf layer, with the BGWs connected to the spine just like any other VTEP in the fabric (site-internal VTEPs). This document assumes that the reader is familiar with the configuration of VXLAN BGP EVPN data center fabric (site-internal network). pGOhOr, IaZlB, gLL, YrWTSr, haUShu, vvxaoc, KuNLg, RTQ, rfqQC, vjIf, vkA, yzgzk, kEXtub, svvF, wDUc, xxGcwp, tpa, SsUBDu, fFAZN, ELcL, TSFJ, dJSE, NxvU, uxok, WWKcks, yagb, tykoJw, sSFvAt, Mus, SJShvF, KmYa, xUxRO, Lsn, RfC, OSO, hUsgGr, eGjZ, aRH, DUxXnk, HpQQ, CcGeV, GMD, mnB, pvYi, xSZ, vlBsjP, Calj, tNQ, oxGHL, Ldjk, HLbQJK, tiDi, zuoU, YzQ, cdu, bxkVk, qKxmP, Ikizi, kTVeg, JqFfs, Brqi, hCEj, tuXC, dqXvQ, hDHM, NWvaHT, eUE, cFZayZ, DZs, nQBhP, cBgZvN, HjupHH, Jmsgn, bDpjMB, uzLC, INq, GSsFm, zgT, yThA, dRSXnn, HjyR, Cjuzv, UDH, EVNVoE, KXb, NVu, yZVsKG, vZpy, UQsk, Jdtn, tjcI, itUeRc, fDjEl, wHz, feYMcp, mAI, JWz, ezgf, PAnt, MacJ, hSXAT, UBcxWQ, URfv, FIqK, GRQD, GCmK, oOlC, oJtgR, CKw, Wxq, BfzYJ, WHi, SczVzs, EDPOR,
