IPv6 VPN over MPLS
IPv6 VPN over MPLS, also known as 6VPE, uses the existing MPLS IPv4 core infrastructure for IPv6
transport to enable IPv6 sites to communicate over an MPLS IPv4 core network using MPLS label switch
paths (LSPs). 6VPE relies on MP-BGP extensions in the IPv4 network configuration on the PE router to
exchange IPv6 reachability information. Edge routers are configured to be dual-stacks running both IPv4
and IPv6, and use the IPv4 mapped IPv6 address for IPv6 prefix reachability exchange.
The following topics tell you how you can use Cisco ANA to view and manage 6PVE implementations.
