Upstream BGP community support

Sun Nov 1 00:30:38 UTC 2009

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 :)
