bgpd crashes on long AS-path
I admin multipe openbgp servers for a handful of companies. On Monday (16th), I was notified that bgp had crashed on 4 out of the 8 machines. The bgpd crashed because it was being advertised a route with a long AS path (> 255). The incident was global, and more information can be found on the nanog thread :- http://www.merit.edu/mail.archives/nanog/msg15469.html It seems instances where peers advertise an invalid route like this are quite common. Unfortunately I can't see an option in openbgpd.conf to check the length of an AS and hence filter it out. Would it be possible to have functionality similar to Cisco IOS "maxas limit", so I could filter the route? I can't rely on my upstreams to do the sanity check and it's fatal if the route hits openbgp. Thanks, Jules
Re: Problems with (em) on Nexcom NSA 1180
I now know the reason for the intel network cards failing to initalise on OpenBSD. OpenBSD doesn't have a driver for the bridge chipset (PLX) therefore cannot utilise the LAN ports on board. I have checked the PLX website and their doesn't appear to be any support for OpenBSD.

I have used other Nexcom units with OpenBSD, including the NSA1086 and DNA840 - both make ideal routing platforms when used with bgp/ospf/ carp. Thanks, Jules
