1.4.6 Cross-Domain MPLS L3VPN Configuration Example — Option C

I. Network requirements

CE1 and CE2 belong to the same VPN. CE1 accesses the MPLS network through PE1

in AS100; and CE2 accesses the MPLS network through PE2 in AS200.

The example adopts Option C to implement a cross-domain MPLS L3VPN, that is, the

VPN routing is managed by the Multi-hop MP-EBGP which advertise label VPN-IPv4

routes between PEs.
