3.18.5 Example for Configuring Inter-AS VPN Option B
After establishing the single-hop MP-EBGP peer relationship between ASBRs, you can
implement the inter-AS VPN OptionB solution.
Networking Requirements
As shown in Figure 3-6, the CE1 and the CE2 belong to the same VPN. The CE1 accesses the
network through the PE1 in the AS 100. The CE2 accesses the network through the PE2 in the
AS 200.
The inter-AS BGP/MPLS IP VPN is implemented using Option B:
l ASBR 1 exchange VPN-IPv4 routes with ASBR 2 by MP-EBGP.
l ASBR does not perform VPN target filtering on the received VPN-IPv4 routes.
