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...)
This is correct.
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?
It shouldn't be a factor in BGP. BGP is used to manage route announcements and not the engineering short comings of your network, if you plan things and configure BGP correctly you'll find you can do what you are asking here.
