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 VPN-IPv4 routes by MP-EBGP.

z

ASBRs do not perform VPN target filtering of received VPN-IPv4 routes.
