Configuration procedure
Configure an IGP on the MPLS backbone to ensure IP connectivity in the backbone.
1.
This example uses OSPF. (Details not shown.)
The 32-bit loopback interface address used as the LSR ID must be advertised by OSPF.
After you complete the configurations, each ASBR PE and the PE in the same AS can establish
OSPF adjacencies. Issue the display ospf peer command. The output shows that the adjacencies
reach Full state, and that PEs can learn the routes to the loopback interfaces of each other.
Each ASBR PE and the PE in the same AS can ping each other.
Configure basic MPLS and MPLS LDP on the MPLS backbone to establish LDP LSPs:
2.
# Configure basic MPLS on PE 1 and enable MPLS LDP on the interface connected to ASBR PE 1.
