Configure an AGG as an RR

Configure an AGG as an RR

In the inter-AS seamless MPLS networking, an AGG is configured as an RR to advertise the route to the CSG's loopback interface to an AGG ASBR, and the AGG ASBR advertises the route to the core layer over an EBGP peer connection. The loopback route information is used to establish an MP-EBGP peer relationship between each CSG and MASG.

Procedure

  1. Run:

    system-view

    The system view is displayed.

  2. Run:

    bgp { as-number-plain | as-number-dot }

    The BGP view is displayed.

  3. Run:

    ipv4-family unicast

    The IPv4 unicast address family view is displayed.

  4. Run:

    peer { ipv4-address | group-name } reflect-client

    An RR is configured, and the CSG and core ASBR are specified as clients.

  5. Run:

    peer { ipv4-address | group-name } next-hop-local

    The device is configured to use its own IP address as the next-hop address of routes when advertising these routes.

    To enable the AGG to advertise routes with the next-hop address set to a local address, run the peer next-hop-local command on the AGG.

  6. Run:

    commit

    The configuration is committed.
