Not sure this has been posted already as it was first aired in June 08 but for a great overview of Routing and Routing Protocols for CCNA students by Cisco CCIE Routing expert Luc Agossa ("Cisco Engineering Manager" - < woah - just imagine what he gets paid! > ) ....
From the basics, the first 15 mins get you upto speed on the whole concept..... See how long you last before you get lost from then on! ( floating staic routes ... How do you authenticate routing protocol updates between routers prior to update for security purposes - "YWhat ?!?" )
37 mins total and ( I think ) should be in every budding CCNA's arsenal. Local routing/vlans to continent to continent routing and why you choose the routing protocol you do.
[ WARNING: For UK viewers, there is an awful lot of "rowting" and "rowters" which really started to bug the hell out of me - US: we say "rooting" and "rooters" so you can imagine the annoyance after 37 mins of it ]

Interior and Exterior is one thing that I had never got my head around but in one quick sentance, it all made sense.
Appologies if you have already been made aware of this vid.
