But you could,  it isn't hard to dump a BGP view into a box from a

It's harder than it looks, given the number of people who pop up on this list
and ask how to get BGP to Do The Right Thing when 2 paths are the same length
but vastly differing in bandwidth, number-of-actual-hops, and/or latency....
