Site 1 accesses the network throughPE 1 in AS 100 and Site 2 accesses the network through PE 2 in AS 600.■ PEs in the same AS runs IS-IS between them.■ PE 1 and ASBR-PE 1 exchange labeled IPv4 routes by MP-IBGP.■ PE 2 and ASBR-PE 2 exchange labeled IPv4 routes by MP-IBGP.■ PE 1 and PE 2 are MP-EBGP peers.■ ASBR-PE 1 and ASBR-PE 2 use their respective routing policies and label theroutes received from each other.■ ASBR-PE 1 and ASBR-PE 2 use MP-EBGP to exchange labeled IPv4 routes.
