Nokia – SROS: 6PE Tunneling IPv6 over IPv4/MPLS.
“In the 6PE architecture, the PE routers of the IPv4/MPLS core run a dual stack of IPv4/IPv6 and exchange the IPv6 routes using MP-BGP (Multiprotocol BGP).
IPv6 routes learned through MP-BGP on the PE routers have their next-hop
resolved through an LDP tunnel.”
