Or until people who are still running multi-year old cisco code actually upgrade? This seems to primarily impact: 1) Old cisco code 2) PC based bgp daemons Both of which likely just need to be upgraded. I actually suspect that a lot of people who dropped their bgp sessions did not notice something happened, and still will not upgrade their code. I searched the archives, some variations of this have happened since 2001. There's been a few PSIRT and other issues since then, I suspect these people don't even know they have a bgp speaking device anymore.
While at it - perhaps others wish to join this bugid so as to enhance IOS: CSCso47162 Bug Details BGP-6-ASPATH message should print offending prefix(es) None Symptoms Syslog message below doesn't print info about offending prefix(es) %BGP-6-ASPATH: Invalid AS path [chars] received from [int]: [chars] Further Problem Description Examples of such a message :%BGP-6-ASPATH: Long AS path 64501 64501 65000 65000 received from x.x.x.x: Morethan configured MAXAS-LIMIT
%BGP-6-ASPATH: Invalid AS path (64721) 64700 64720 65400 65231 received from x.x.x.x: Non confederation peer
I opened it in March 2008 and the more people who bug Cisco to implement this sev 6 request - the better off we will all be in the future.
