Configuration procedure
1. Configure IGP on the MPLS backbone.
This example uses OSPF. (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 PEs and ASBR-PEs in the same AS have
learned the routes to the loopback interfaces of each other. Verify that each ASBR-PE and the PE in
the same AS can ping each other. (Details not shown.)
2. Configure basic MPLS and MPLS LDP on the MPLS backbone to establish LDP LSPs:
# Configure basic MPLS on PE 1, and enable MPLS LDP on the interface connected to ASBR-PE 1.
