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:
