Configuration procedure
1. Configure an IGP on each MPLS backbone to ensure IP connectivity within the backbone.
This example uses OSPF. Be sure to advertise the route to the 32-bit loopback interface
address of each router through SPF. Use the loopback interface address of a router as the
router's LSR ID. (Details not shown.)
# Execute the display ospf peer command to verify that each ASBR-PE has established an
OSPF adjacency in Full state with the PE in the same AS, and that the PEs and ASBR-PEs in
the same AS have learned the routes to the loopback interfaces of each other. Execute the
ping command to verify that the PEs and ASBR-PEs in the same AS can ping each other.
(Details not shown.)
2. Configure basic MPLS and enable MPLS LDP on each MPLS backbone to establish LDP LSPs:
# Configure basic MPLS on PE 1, and enable MPLS LDP for both PE 1 and the interface
connected to ASBR-PE 1.

[PE1-Pos2/2/0] mpls enable
[PE1-Pos2/2/0] mpls ldp enable
[PE1-Pos2/2/0] quit
# Configure basic MPLS on ASBR-PE 1, and enable MPLS LDP for both ASBR-PE 1 and the
interface connected to PE 1.

[ASBR-PE1-Pos2/2/0] mpls enable
[ASBR-PE1-Pos2/2/0] mpls ldp enable
[ASBR-PE1-Pos2/2/0] quit
# Configure basic MPLS on ASBR-PE 2, and enable MPLS LDP for both ASBR-PE 2 and the
interface connected to PE 2.
