The output shows that PE 1 has routes to the remote CEs. Output on PE 2 is similar.
# 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.
