Configuring IPv6 MPLS L3VPN

IPv6 MPLS L3VPN overview

MPLS L3VPN applies to the IPv4 environment. It uses BGP to advertise IPv4 VPN routes and uses MPLS
to forward IPv4 VPN packets on the service provider backbone.
IPv6 MPLS L3VPN functions similarly. It uses BGP to advertise IPv6 VPN routes and uses MPLS to forward
IPv6 VPN packets on the service provider backbone.
Figure 80 shows the typical IPv6 MPLS L3VPN model. At present, the service provider backbone in the
IPv6 MPLS L3VPN model is an IPv4 network. IPv6 runs inside the VPNs and between CEs and PEs.
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.
