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 OSPF. Use the loopback interface address of a router as the router's LSR ID.
(Details not shown.)
# Each ASBR-PE and the PE in the same AS can establish an OSPF adjacency. 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.
