Configuration procedure
1.
Configure IGP on the MPLS backbone to implement the connectivity in the 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.
