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 loopback routes from one another. The loopback route information is used to establish an MP-IBPG peer relationship between each CSG and MASG.

Procedure

Run system-view
The system view is displayed.
Run bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
Run ipv4-family unicast
The IPv4 unicast address family view is displayed.
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.
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.
Run commit
The configuration is committed.
