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.

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? > >Andre' > >[email protected] >
