In the words of Iljitsch van Beijnum's book "BGP", which I was reading over Easter (I know, I'm a sad person):

"If you are implementing a large-scale IP network or have unusual requirements, you should definitely read up on all the protocols so you can make an informed decision. However, most small-to-medium sized networks running just IP should go ahead and select OSPF: it does the job, doesn't have any huge disadvantages, and is readily available."

What a terrible thing to be reading over easter :-) One advantage of using IS-IS is that if you're running both IPv4 and IPv6 on a network, you only need to run the one IGP for both. Doing both woth OSPF requires OSPFv2 and OSPFv3 :-( I did see a very good presentation some time ago (which may very well have been the AOL one that Joe mentioned) that detailed the transition to IS-IS where the network was live at the time. From memory, the primary reason for the change was the desire to move to an MPLS-capable network. Cheers, Gordon
