Heh, I'd like to add that wether you use IS-IS or OSPF is also a matter of
your network design and topology, learning a new routing protocol is always
fun :) and could lead to a much robust and resillient network.

On another subject I've been trying to find information about TE and BGP,
because all of our peers act as BGP4 AS... is it possible or do I have to do
BGP to OSPF (In my case) and apply all my TE rules there, if so, how does it
impact traffic flows coming from the BGP routers?
