this might be of interest to some. we found a few weeks ago that we were suddenly on the "bad guys" list at merit, routing-problems@merit.edu. we were consistantly making the top ten offenders of "largest sources of bgp instability". we had upgraded to a new version of code in our peer router in san jose that had "lost" the fix to bgp to stop these excessive withdraws which had been discussed on nanog some time ago. we got a new image with the fix rolled back in 2 days ago and will be deploying soon. i don't know what version everyone is running but if you're making this list consistantly you might check with your vendor to see if your version of code is lacking this fix. here is yesterday's list for those that don't subscribe to routing-problems: Largest Sources of BGP Instability ---------------------------------- (announcements + withdraws = total) 1. ANS (AS1673) at Mae-East 7124 + 276413 = 283537 BGP prefix updates 2. INSnetUSA (AS6660) at Mae-East 11 + 250384 = 250395 BGP prefix updates 3.
