--> LFIB stands for Label Forwarding Information Base.
--> LFIB is similar to FIB( used to forward IP Packets) in router used to forward incoming labeled packets.
--> FIB lookup will be done by the router when the router receives IP packet and LFIB lookup when the router receives Label.
--> Per-Flow load balancing is used in LFIB when there is more than one path to reach the destination.
--> LFIB contains following entries,
i) One Local Label or Incoming Label
ii) One or more Remote Labels based upon how many paths to reach the destination
iii) Prefix and Prefix Length
iv) One or more outgoing interfaces.
--> In order to verify LFIB table in the router, we use the following command
Router # show mpls forwading-table
