Sean,
A fine practical analysis of the two.
One thing about IS-IS that is quite different from OSPF and all the other IGPs
is that the neighbor traffic is not in IP but instead is done at layer 2. Some
say this is a good thing. I have never run into a case where I couldn't get it
to do what I wanted, but always suspected there would be. Would this force ATM
links to move to the less efficient SNAP based encoding (if so, there's 4% of
your bandwidth)?
