FIB and adjacency table

Hi,

Can any one help on distinguishing the FIB and adjacency table and how adjacency table is built?

FIB is basically mirror of RIB so assume it contains mirror of routing table.The FIB maintains next-hop address information based on the information in the IP routing table.The other part of the process is the adjacency table, the adjacency table maintains L2 next hop addresses for all FIB entries.

Thanks

I see you got a silver star ajay, nice going!

Here is a link to a thread that explains this topic rather well. It was done by Peter Paulach. Sorry if I butchered your

last name Peter.

Hey John,

My last name spells "Palúch" in Slovak but don't worry I am accustomed to the fact that on international forums, it is difficult to keep spellings of names and surnames correct - I have myself made a mistake a couple of times, I believe.

Anyway, thank you very much for your nice words!

Best regards,

Peter
