It's just wording. "backbone connected interfaces" means "interior interfaces on which you run your IGP". For example: int POS1/0/0 description connection to another backbone location ip address foo bar isis circuit-type level-2-only isis metric 1 level-2 which I think is what Jared means. The terminology to explain the difference between that and actually putting a prefix into your IGP is a bit dense, so a shortcut probably was a reasonable idea. --:) Sean.

Although any other introduction of routing hierarchy is into the routing domain should be, well .. even more interesting.

Recall the BGP rule: one iBGP speaker mustn't advertise routes to another iBGP speaker if they were learned from a third iBGP speaker. I'd be interested in hearing from anyone that *really* operates a network of more than a few routers and is using iBGP as an IGP .. if you can find the time to send me an email :-) -danny

Overkill, surely? In fact, you not only don't need to do so, you want to avoid doing so. This simply pollutes BGP and you'll need to remove it later at the domain border where you're aggregating anyhow. Tony

Ben, I stand corrected sorry for the mistype. you are right about using bgp as Exterior Gateway Protocol but I have used IBGP internaly on my network in the past.

I'm not about >to go around and change 400 PCs for this, so a router config would really >be preferable. First off, the guys that *really* know this stuff are on the Samba list. Mickeysoft is clueless when it comes to this stuff. The first question is, if there is a Primary Domain Controller involved anywhere? The next question is, what are you plannning for your gateway machines? WINS *may* be required, but a Samba Server can fulfill that function quite well. You'll also need to set up LMHOSTS files. Your main problem is that SMB protocols do not route easily. In fact, any version less than WinNT will not route out of its own sub-net. If any PCs, are running Win95 then you'll need a pair of hosts to route the SMB protocols for them. This could be a WinNTserver, but I prefer a Linux host running Samba suite (you won't have to re-boot on each config change and you can run it headless-remote). Datacom Warehouse may have a box thatll help you, but I'd look into a "blue cube". ___________________________________________________ Roeland M.J.

IGPs in use

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?
