3.4.6 Cross-Domain BGP/MPLS VPN 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 BGP/MPLS VPN, that is,
the VPN routing is managed by the Multi-hop MP-EBGP which advertise label
VPN-IPv4 routes between PEs.
