Well, sure, but why should I _have_ to? I thought we, in part, pay the big bucks for routers that are supposed to figure some of this stuff out on their own without having to "band-aid" things with AS path manipulations, etc. On Fri, 8 Nov 1996, Deepak Jain wrote:
Can't you adjust your metrics/weights to prefer the low speed links less?

With all the recent talk about BGP, etc., I thought I'd see if anybody knows the reasoning behind a particular short-coming of BGP that I've noticed and found particularly bothersome...
We peer, using BGP, with several "backbone" provider networks for transit purposes. Some of these links are "faster" than others (e.g. T-3 vs. multiple T-1 and single T-1) for various reasons. If our router sees a route to a particular destination via a "high-speed" link and a "low- speed" link that has the _same_ number of AS "hops", it picks the link with the "lowest" IP address! (At least that's what I'm told and what I observe...)
Why doesn't BGP pick the link with the highest bandwidth, or, better yet, pick the link with the highest bandwidth AND least congestion to label as the "best" available route? The needed information is avail- able in the router (and if it was somebody doing BGP from a host that was separate from the box with the interfaces, well, then too bad I guess) and can't be _that_ hard to incorporate can it?
I'll get off my soapbox now...
