Layer 2 circuit, Layer 2 VPN, and VPLS services with BGP labeled unicast

Layer 2 circuit, Layer 2 VPN, and VPLS services with BGP labeled unicast as the transport protocol. BGP PIC Edge using the BGP labeled unicast transport protocol helps to protect traffic failures over border nodes (ABR and ASBR) in multi-domain networks. Multi-domain networks are typically used in metro-aggregation and mobile backhaul networks designs. A prerequisite for BGP PIC Edge protection is to program the Packet Forwarding Engine (PFE) with expanded next-hop hierarchy.
