Is this really true? All I'm asking for is that the route a router considers to be "best" be picked by something a little more rational than the ordinate order of its IP address relative to another link. I don't see a flap situation at all here -- only that a decision to route a packet may change more frequently based on load.
A decision to route a packet may change more frequently based on load. And those decisions are propogated and acted upon by other routers. And they send traffic down those links. And the load on those links changes. And you make a new decision to route a packet based on the new load. | _ | /| | /\ / | / \ / | -^\/\ / \ / | \/ \ / | \ / | \/ | | +---------------------------------------------- Unless you have a model which is provably resilient to these sorts of feedback loops (which, to my understanding, BGP is not), then playing these sort of tricks is a young man's game, and one guaranteed not to leave him young (or employed) for long. Statically adjust the preference on your links and count yourself lucky. 8^) __ Todd Graham Lewis Linux!
