Who populate LFIB

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.
