4.11.4 Example for Configuring Inter-AS IPv6 VPN Option A
Context
As shown in Figure 4-5, CE1 and CE2 belong to the same VPN. CE1 accesses PE1 through AS
100, and CE2 accesses PE2 through AS 200.
The inter-AS BGP/MPLS IPv6 VPN is implemented through Option A. That is, the VRF-to-
VRF method is used to manage VPN routes.
