: Try netstat -rA and see what it shows for netmask. You've got one
: default route with the usual netmask, and the other one is with some
: strange netmask.
Since network is down, option -n have to be used. I do not know if this makes
different to you:
# netstat -rAn

P.S. I think this can be reproduced on any FreeBSD host. We have more than
50 FreeBSD hosts running here, and I can use "route add something..."
to screw up every host. So, it is not a particular configuration
on my site to triggering the bug. I think it is a general problem.
