Configuring a Client PE to Establish an MP-IBGP Peer Relationship with an RR

You can configure a PE to establish an MP-IBGP peer relationship with an RR so that the PE can receive VPNv4 routes reflected by the RR.

A PE or P can function as an RR on the backbone network.

Run system-view
The system view is displayed.
Run bgp as-number
The BGP view is displayed.
Run peer peer-ipv4-address as-number as-number
The RR is specified as a BGP peer.
Run peer peer-ipv4-address connect-interface loopback interface-number
The interface used to establish a TCP connection is specified.

A client PE must use the loopback interface address with a 32-bit mask to establish an MP-IBGP peer relationship with the RR so that routes can recurse to a tunnel.
Run ipv4-family vpnv4
The BGP-VPNv4 address family view is displayed.
Run peer peer-ipv4-address enable
The function to exchange VPNv4 routes with the RR is enabled.
Run commit
The configuration is committed.
