Configuring 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.
Inter-AS MPLS L3VPN is implemented using option A, where the VRF-to-VRF method is used to
manage VPN routes.
The MPLS backbone in each AS runs OSPF.
