Hi Ayush

LFIB is forwarding plane in mpls network, when we enable MPLS, Lable is assigned to each prefixes and that prefix to lable binding table called LIB, LIB is just a control plane, LFIB is populated out of the LIB, the same way FIB created ouf of the RIB.

Please look at below discussion, you might get answer of your questions.
