Hi Akshay,

    The Label Information Base (LIB) in an LSR holds ALL the local labels assigned by that LSR, and a mapping between those labels and the labels received from neighbouring LSRs.

 

The Label Forwarding Information Base (LFIB) holds ONLY those local labels that are currently being used for forwarding. It also has a mapping between these labels and the outgoing labels received from neighbour LSRs, but additionally it also holds the egress interface to be used in forwarding, and the IP next hop address.

 

Hope this helps,

    John
