Large networks all over the world run IS-IS. You won't find an abundance of information on the protocol as you would with OSPF (especially such as John Moy's OSPF book), however it's still a very popular IGP. There's an interesting draft on the differences between OSPF and ISIS which probably wouldn't have been written if IS-IS wasn't used a whole heap: http://ftp.apnic.net/ietf/internet-drafts/draft-bhatia-manral-diff-isis-ospf... As for what networks are running what protocol, you're unlikely to get too much on that sort of info. Chris

What routing protocols do people use on their networks? Particularly inside.

Does anyone in the world actually use IS-IS ?

I am not interested in what network runs what, just how many networks run various protocols.

Rough idea of network size would be nice, and any partcular reasons you prefer one to the other.

thanks for satisfying my curiosity JM -- -----BEGIN PGP PUBLIC KEY BLOCK----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org
