Here is the problem as I see it. Sure some % fo the people using BGP are bright nuff to use some upstreams communities, but sadly many are not. So this ends up breaking one or more networks, who in turn twist more dials causing other changes.. rinse, wash and repeat. But like Randy said who am I to stop anyone from playing... just means those of us with clue will be able to continue to earn a pay check for a very long time still :) -jim On Sat, Oct 31, 2009 at 9:25 PM, Randy Bush <randy@psg.com> wrote:
while i can understand folk's wanting to signal upstream using communities, and i know it's all the rage. one issue needs to be raised.
bgp is a brilliant information hiding protocol. policy is horribly opaque. complexity abounds. and it has unfun consequences, e.g. see tim on wedgies etc.
and this just adds to the complexity and opacity.
so i ain't sayin' don't do it. after all, who would deny you the ability to show off your bgp macho?
just try to minimize its use to only when you *really* need it.
