Re: Why doesn't BGP...

The router really can't see how fast an interface *can* go unless it's maxed out. That's not really useful information in a route-selection decision. It's possible that the packet loss might weight a better path but you would have to be careful about reweighting 20k paths every few minutes... Especially if you pass those decisions on to other routers :) Avi - - - - - - - - - - - - - - - - -
