If you have client --> border router -> route reflector -> all other BGP speakers and the "RR -> BGP speakers" sessions get tripped due to "client sending in too many new routes", then your whole network will fall apart until you can shutdown that initial BGP session (or re-provision the other sessions, which might not work due to "there is no connectivity to the management systems, because, BGP is down"). *Iff* this happens, and you do not have working OOB access including being able to do local config changes on the routers ("all configs are done by the automatization, no local access possible"), such a problem will be extremely messy to recover. Especially figuring out *what* happened, if you have no visibility because the routers have lost the route to your syslog servers.... gert -- "If was one thing all people took for granted, was conviction that if you feed honest figures into a computer, honest figures come out.
