The LIB represents the control plane information for a LSR: Label Switch Router. A label exchange protocol binds labels to routes in the RIB (routing table) and it also exchange the label bindings with other neighbors LSR's. The LIB is the place where the LSR's store the local and received labels. Label exchange protocols are LDP, TDP, MP-BGP and RSVP. Also, the structure of the LIB is Prefix, LSR/Local, Label.
The LFIB represents the data plane for a LSR. It is build from the CEF table + LIB. The LFIB stores the labels used to forward packets, unlike the LIB table that stores all the label bindings. The structure is Inlabel, Outlabel, Next-Hop.
Regarding the other terms, where have you seen this terminology? I suppose that are:
NextHopLabel ForwardingEntry (NHLFE): the next hop LSR.
IncomingLabelMap(ILM): The label received from a LSR, from the Label Mapping message received.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
