BGP Peering and Prefix filterin Question

Mon Oct 29 19:54:02 UTC 2007

I'm suspecting that the customers problem was BGP Flap Damping (or  
Dampening) and that somehow the explanation got lost in translation  
somewhere (I've tried explaining it to some non-engineers sometimes  
and it is a tricky concept for many to grasp for some reason...)

Whether its "normal" or a good idea or who does / doesn't do it is a  
topic fraught with religion....

She'd even given herself a middle initial - X - which stood for  
"someone who has a cool and exciting middle name".
