Enabling Client-to-Client Reflection for the BGP L2VPN EVPN Address Family

Client-to-client reflection enables routes from one client to be reflected to other clients by the host device on which it is configured. Client-to-client reflection is enabled by default for the BGP L2VPN EVPN address family.

The following task re-enables client-to-client reflection for the BGP L2VPN EVPN address family if it has been disabled.

  1. Enter global configuration mode.
    device# configure terminal
  2. Enable BGP routing.
    device(config)# router bgp
  3. Configure the autonomous system number (ASN).
    device(config-bgp-router)# local-as 656
  4. Specify the ASN for the neighbor device.
    device(config-bgp-router)# neighbor 1.1.1.35 remote-as 656
  5. Enable BGP L2VPN EVPN address family configuration mode.
    device(config-bgp-router)# address-family l2vpn evpn
  6. Activate the neighbor to enable the exchange of information with the neighbor.
    device(config-bgp-l2vpn-evpn)# neighbor 1.1.1.35 activate
    
  7. Enable the sending of both standard and extended attributes in updates to the specified BGP neighbor.
    device(config-bgp-l2vpn-evpn)# neighbor 1.1.1.35 send-community both
  8. Enable client-to-client reflection.
    device(config-bgp-l2vpn-evpn)# client-to-client-reflection
    

The following example re-enables client-to-client reflection for the BGP L2VPN EVPN address family if it has been disabled.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# local-as 656
device(config-bgp-router)# neighbor 1.1.1.35 remote-as 656
device(config-bgp-router)# address-family l2vpn evpn
device(config-bgp-l2vpn-evpn)# neighbor 1.1.1.35 activate
device(config-bgp-l2vpn-evpn)# neighbor 1.1.1.35 send-community both
device(config-bgp-l2vpn-evpn)# client-to-client-reflection
