When MPLS (Multiprotocol Label Switching) LFIB (Label Forwarding Information Base) lookup fails, typical forwarding behavior is to drop such packets. This feature allows fallback IP lookup when MPLS lookup fails and forwards traffic to an IP path by looking up the packet’s destination IP address in the route table if the network topologies have labeled paths programmed & IP based routes are also available for the same destination. This feature is also supported with optimized IPv4 8-to-1 route scale compression.
