Have you tried restarting routing? /etc/rc.d/routing restart I have found the same symptoms with other outages and not performing the above. I have done "/etc/rc.d/netif restart" and "/etc/rc.d/routing restart". Wtih using these commands, I have found this to be successful in restoring network interfaces communication, without having to reboot. Hope this helps.
