Routing protocols and how they operate......

iwannaknowIT

I've got this sub-netting down pat and will be taking my CCNA Cert in November. I want to know if anyone can suggest study material concentrating primarily on routing protocols and how they determine their inter-networking of sending packets.I have read Todd's 6th Edition,along with Chris Bryant's vid,but I need a bit more in depth discussion on routing protocols(RIP,RIPv2,IGRP are just a few that are mentioned quite often in Todd's book),but looking at practice questions,I see that there will be quite a bit pertaining to routing protocols and the effects they'll have with packet switching,updates,and so forth....

Thanks for any and all suggestions.......
