correct

I've seen cases where one BGP link really never is the best interface 
(with a pair of 'big 3' ISP's) where one of them was never the best route, 
it turned out on investigation that our connection to them had 5 more hops 
then the other one, even to other locations within that ISP. a bit if 
yelling (and a few threats to move business elsewhere) finally got them to 
fix the problem.
