That was a different one, but I didn't have that data readily available. The cisco/bay bug I was thinking of was when Cisco's kept reseting all their BGP sessions when they saw a particular announcement from Bay routers.
IIRC (or maybe we're thinking of different outages), it was reversed. There was an advertisement with a malformed AS_PATH attribute "out there", Cisco's accepted it and passed it on (still in malformed form), but Bay's (and some other non-Cisco implementations, such as gated) correctly issued a Notify message and dropped the session upon receipt of the malformed advertisement. I believe there were two such outages (separated by a year or so) before Cisco fixed the bug. -- Brett
