Configuring MPLS L3VPN inter-AS option A
Network requirements
CE 1 and CE 2 belong to the same VPN. CE 1 accesses the network through PE 1 in AS 100, and
CE 2 accesses the network through PE 2 in AS 200.
Configure MPLS L3VPN inter-AS option A, and use the VRF-to-VRF method to manage VPN routes.
Run OSPF on the MPLS backbone in each AS.

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:
