Example for Configuring Inter-Provider VPN Option A
Network requirements
z
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.
z
Inter-provider MPLS L3VPN is implemented using option A. That is, the VRF-to-VRF method is
used to manage VPN routes.
z
The MPLS backbone in each AS runs OSPF.

Configuration procedure
1) Configure IGP on the MPLS backbone, implementing the connectivity in the backbone
This example uses OSPF. The detailed configuration steps are omitted.
