This feature introduces per-nexthop MPLS label allocation for the IPv4-unicast default-route and the IPv6-unicast default-route. Previously, BGP-VPN VRFs only supported a per-VRF label scheme. With a per-VRF label scheme, each BGP-VPN supported AFI-SAFI (i.e. IPv4-unicast and IPv6-unicast) in the BGP-VPN VRF is allocated a single "per-VRF" label that will be shared by all the AFI-SAFI’s routes. When the routes are exported as BGP-VPN routes, all the routes will be exported with the same "per-VRF" VPN label. In the Label FIB (LFIB), each allocated "per-VRF" label is associated with an ip-lookup action inside their corresponding BGP-VPN VRF.
