Configuring IPv6 MPLS L3VPN inter-AS option C
Network requirements
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. PEs in the same AS run IS-IS.
PE 1 and ASBR-PE 1 exchange labeled IPv4 routes by IBGP. PE 2 and ASBR-PE 2 exchange labeled IPv4
routes by IBGP. PE 1 and PE 2 are MP-EBGP peers to exchange VPNv6 routes.
ASBR-PE 1 and ASBR-PE 2 use their respective routing policies and label the routes received from each
other.
ASBR-PE 1 and ASBR-PE 2 use EBGP to exchange labeled IPv4 routes.
