Configuring an AGG and a Core ABR as RRs

Configuring an AGG and a Core ABR as RRs

In the intra-AS seamless MPLS networking, the AGG and core ABR can be configured as RRs so that CSGs and MASGs can learn one another's loopback routes. The loopback route information is used to establish an MP-IBPG 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 peer is specified as a client.

    The AGG's clients are its connected CSG and core ABR. The core ABR's clients are its connected AGG and MASG.

  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 or core ABR to advertise routes with the next-hop address set to a local address, run the peer next-hop-local command on the AGG or core ABR.

  6. Run:

    commit

    The configuration is committed.
