To enable the CSG and MASG to learn loopback routes to each other on an intra-AS seamless MPLS network, configure an AGG and a core ABR as reflectors, specify a CSG and the core ABR as the AGG's clients, and specify the AGG and an MASG as the core ABR's clients. The loopback routes can be used to set up an MP-IBGP peer relationship between the CSG and MASG.
The system view is displayed.
The BGP view is displayed.
The IPv4 unicast address family view is displayed.
An RR is configured, and the peer is specified as a client.
By default, no RR or specified client is configured for BGP.
BGP is configured to use its own IP address as the next hops of routes when advertising these routes to its clients.
By default, when BGP advertises routes to an EBGP peer, it uses its own IP address as the next hops. When BGP advertises routes to an IBGP peer, it does not change the next hop attribute.
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.
