Configuring EVPN VXLAN External Connectivity Configuring BGP on a Border VTEP for External Connectivity with MPLS Layer 3 VPN Command or Action Purpose Step 18 address-family vpnv4 Example: Device(config-router)# address-family vpnv4 Specifies the VPNv4 address family and enters address family configuration mode. Step 19 import l2vpn evpn re-originate Example: Device(config-router-af)# import l2vpn evpn re-originate Reoriginates the EVPN routes imported from the EVPN fabric into the VPNv4 address family as VPNv4 routes and distributes them to the external network. Step 20 neighbor ip-address activate Example:
Device(config-router-af)# neighbor 172.16.255.103 activate Enables the exchange information from a BGP neighbor. Use the IP address of the external MPLS network router as the neighbor IP address. Step 21 neighbor ip-address send-community [both | extended | standard] Example: Device(config-router-af)# neighbor 172.16.255.103 send-community both Specifies the communities attribute sent to a BGP neighbor. Use the IP address of the external MPLS network router as the neighbor IP address. Note Use either of extended or both keywords. External connectivity cannot be established when you use the standard keyword. Step 22 neighbor {ip-address | peer-group-name} next-hop-self [ all] Example:
Device(config-router-af)# neighbor ip-address next-hop-self all Configures the router as the next hop for a BGP-speaking neighbor or peer group. The all keyword is mandatory when implementing external connectivity through iBGP, where the EVPN fabric and the MPLS network are in the same BGP autonomous system number. The all keyword is optional when implementing external connectivity through eBGP, where the EVPN fabric and the MPLS network are in different BGP autonomous system numbers. Step 23 exit-address-family Example: Device(config-router-af)# exit-address-family Exits address family configuration mode and returns to router configuration mode. Step 24 address-family vpnv6 Example:
Device(config-router)# address-family vpnv6 Specifies the VPNv6 address family and enters address family configuration mode. Configuring EVPN VXLAN External Connectivity 14
