IPv6 Provider Edge Router over MPLS (6PE)

6PE allows IPv6 domains to communicate with each other over an IPv4 MPLS core network. This
architecture requires no backbone infrastructure upgrades and no re-configuration of core routers,
because forwarding is purely based on MPLS labels. 6PE is a cost effective solution for IPv6
deployment.
