# Verify that CEs of the same VPN can ping each other, and CEs of different VPNs cannot ping each
other. For example, CE 1 can ping CE 3 (2001:3::1), but cannot ping CE 4 (2001:4::1). (Details not
shown.)
Configuring IPv6 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 IPv6 MPLS L3VPN inter-AS option A, and use the VRF-to-VRF method to manage VPN routes.
Run OSPF on the MPLS backbone of each AS.

Configuration procedure
1.
Configure an IGP on each MPLS backbone to ensure IP connectivity within the backbone:
This example uses OSPF. (Details not shown.)
