6) Verify your configurations
After you complete the above configurations, the CEs should be able to learn the interface routes from
each other and ping each other.
Example for Configuring Inter-Provider VPN Option B
Network requirements
z
Site 1 and Site 2 belong to the same VPN. CE 1 of Site 1 accesses the network through PE 1 in AS
100 and CE 2 of Site 2 accesses the network through PE 2 in AS 600.
z
PEs in the same AS runs IS-IS between them.
z
PE 1 and ASBR-PE 1 exchange labeled IPv4 routes by MP-IBGP.
z
PE 2 and ASBR-PE 2 exchange labeled IPv4 routes by MP-IBGP.
z
ASBR-PE 1 and ASBR-PE 2 exchange labeled IPv4 routes by MP-EBGP.
z
ASBRs do not perform VPN target filtering of received VPN-IPv4 routes.
