Is there an overview on what the dominantly used interior routing protocols are percentagewise in large AS backbones (IBGP, OSPF, IGRP, EIGRP, IS-IS, any?). I don't want to start religous wars on what's the best protocol, I'm rather interested if there is an overview available on the facts of protocols used. Is there an "objective" (vendor-independent) feature-based overview on the compared advantages/disadvantages (especially regarding redistribution) of the various protocols that goes with those numbers?

No religious wars here... I believe in using the best tool or combination
of tools available to get the job done (and be at least marginally
maintainable for the immediate future).
We utilize a sballocate from a route subnet (/22) for all linkages between
our core routers and assign a Loopback 9 interface (with a /32 mask) from
the same subnet for each core router. We utilize an IGP (EIGRP converting
to OSPF) to carry information ONLY about this network and our EBGP linkage
networks. All of the core routers are fully meshed iBGP and we utilize
route maps to change the next hop information to the Loopback 9 interface
address if the next-hop is not in the set of routes carried on the IGP.
This setup provides extremely fast convergence, very little chatter, and
easy maintenance.
Contact me offline if you want some examples.
