Description Heikki Suonsivu 1997-08-16 19:40:01 UTC 
Without any obvious reason one of the neighbour routers disappears and 
gateway route is not ours is printed by kernel.

arp -a shows 194.100.0.193 "incomplete"

I looked back the logs and found this, this seems to be the first time
the problem appeared, but I am not yet sure whether reachability
was lost right here.  Restarting gated solved the problem.

How-To-Repeat: 
I do not know yet, this has been seen only once this far.
Comment 1 fenner 1997-08-16 22:00:57 UTC 
If this is repeatable, can you follow up with what "route get 194.100.0.193"
says when the problem occurs?

Thanks,
  Bill
