Thanks to everyone who offered advice and links to resources. The
information I've gathered with your help will greatly assist me moving
forward, regardless of our decision on which protocol to use.

There are currently a few projects that we're doing which prompted us to
take a look at how we're doing routing, both IGP and EGP. We're altering our

Isn't that because Dave re-wrote all of the IS-IS code? ;-)

Daniel, in short, we've found ISIS to be slightly easier to maintain and

It is a dangerous thing when, in the course of engineering,
you have a solution looking for a problem, instead of a problem
looking for a solution.
I'd say that the biggest benefit in using IS-IS over OSPF is
the tuning of route metrics, but aside from that, I'd say that

We're currently running OSPF. Believe me, I understand that switching
IGP's is not a simple undertaking. There are several benefits that I'm
looking at, some of which have already been mentioned in replies to my
original thread. Security is one, the other being IPv6 support. I'm
going to have to t

Why are you trying to build a case...? Would you already have

Can we expand this to include enterprise networks as well? The University
that I work for is planning to do a switch-over from OSPF to ISIS, but
I'd like to know if we're really a one off.

All,
Can anyone point me to information on what the top N service providers
are using for their IGP? I'm trying to build a case for switching from
OSPF to IS-IS. Those on this list who are currently running IS-IS, do
you find better scalability and stability running IS-IS than OSPF? I
