Example for Configuring Inter-Provider VPN Option C
Network requirements
z
Site 1 and Site 2 belong to the same VPN. Site 1 accesses the network through PE 1 in AS 100 and
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
PE 1 and PE 2 are MP-EBGP peers.
z
ASBR-PE 1 and ASBR-PE 2 use their respective routing policies and label the routes received
from each other.
z
ASBR-PE 1 and ASBR-PE 2 use MP-EBGP to exchange labeled IPv4 routes.
