As for what networks are running what protocol, you're
unlikely to get
too much on that sort of info.
AOL's transport network runs IS-IS (there was a presentation about their transition from OSPF at a semi-recent NANOG). MFN/AboveNet did a similar transition while I was there. We run IS-IS as our IGP in our home network (AS 3557), although we still use OSPF in local-scope anycast clusters since it's more straightforward to find ways of supporting it on FreeBSD.

I stand corrected. In this case, I wonder if it's the exception rather than the norm that large carriers protect things such as their IGP then? ------------------------------------------------------------------------------ "This communication, including any attachments, is confidential.

I'm quite sure that AOL and MFN protect their IGP, but they do so using link-layer authentication, a link-scope, non-routed protocol (in the case of IS-IS) and by not exposing it to customers or other external entities. That's what we do at ISC. Security by obscurity is no longer in style, maybe. Joe
