Configuring Route Reflection on an ABR

Route reflection on an ABR is used to reflect the VPNv4 routes advertised by the PE or ASBR to other devices in the same AS. As a result, PE does not need to set up BGP peer relationship with ASBR, which simplifies configurations.

  4. Run peer peer-ipv4-address reflect-client

    The ABR is configured as a route reflector. If you need to configure multiple devices as clients, repeatedly run this command.

  5. (Optional) Repeatedly run peer peer-ipv4-address next-hop-local
