Isn't Update Source used only when configuring within a single AS? What I
understood from my reading (although I may have been whacked from lack of
sleep at the time) is that Update Source will have no effect when
configuring with reference to a router in another AS. I do know that
ebgp-multihop is necessary when pointint ot a loopback from another AS.
Am I way off on this one?
