Configuring IPv6 MCE
This chapter describes IPv6 MCE configuration.
IPv6 MPLS L3VPN overview
IPv6 MPLS L3VPN uses BGP to advertise IPv6 VPN routes and uses MPLS to forward IPv6 VPN
packets on the service provider backbone.
Figure 6
shows a typical IPv6 MPLS L3VPN model. The service provider backbone in the IPv6 MPLS
L3VPN model is an IPv4 network. IPv6 runs inside the VPNs and between CE and PE. Therefore,
PEs must support both IPv4 and IPv6. The PE-CE interfaces of a PE run IPv6, and the PE-P
interface of a PE runs IPv4.

IPv6 MCE overview
In IPv6 MPLS L3VPN networks, IPv6 MCE advertises IPv6 routes between internal networks and
PEs, and forwards IPv6 packets. The fundamentals of IPv6 MCE are the same as those of MCE. For
