First of all, it's not obvious to me why you believe the private AS is causing the trouble. As a matter of fact, we saw the same behaviour today morning, except that we _received_ the NOTIFICATION of invalid attribute list from our downstream customer when the full Internet routing table we're advertising to the them (a Cisco router) flapped. I hear the Cisco router's memory is almost full which I thought might be a possible indication of a memory allocation problem. We are running 7.5SR. It's not clear to me whether this was a bug in Cisco or in Juniper. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.
