anyone else seeing very long AS paths?
My bgp speaking devices are a couple of 7200s running 12.2(40).
Not the newest IOS out there, but it's been doing the job just fine up until yesterday.
Yesterday, when that malformed announcement hit my routers they didn't crash,
but they did reset bgp sessions (even though I didn't accept the route) and they kept doing so
until I got my upstream to filter it out.
According to cisco bug toolkit CSCdr54230 should be fixed in 12.2, so obviously it's not enough.
Does anybody know what IOS version has fix this problem, 'cause I couldn't find this info at CCO?
