# CE 1 and CE 2 can ping each other.
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 inter-AS option A MPLS L3VPN, and use the VRF-to-VRF method to manage VPN routes.
Run OSPF on the MPLS backbone of each AS.
