Configuration procedure
1. Configure OSPF on the customer networks.
Configure conventional OSPF on CE 1, Router A, and CE 2 to advertise addresses of the
interfaces as shown in
Router A, and the link between CE 2 and Router A. Execute the display ip routing-table
command to verify that CE 1 and CE 2 have learned the route to each other. (Details not
shown.)
2. Configure MPLS L3VPN on the backbone:
# Configure basic MPLS and MPLS LDP on PE 1 to establish LDP LSPs.

[PE1] interface loopback 0
[PE1-LoopBack0] ip address 1.1.1.9 32

[PE1-Serial2/1/1] mpls enable
[PE1-Serial2/1/1] mpls ldp enable
[PE1-Serial2/1/1] quit
# Configure PE 1 to take PE 2 as an MP-IBGP peer.
