Forwarding MPLS traffic over a non LDP interface
mpls bgp forwarding
*To enable an interface to receive Multiprotocol Label Switching (MPLS) packets when the signaling of MPLS labels is through the use of the Border Gateway Protocol (BGP), use the mpls bgp forwarding command in interface configuration mode. To disable an interface from receiving MPLS packets when the signaling of MPLS labels is through the use of the BGP, use the no form of this command.
This command is automatically generated by BGP for directly connected non loopback neighbors.
