There is that possibility. 'restart' deletes all routing table changes then reapplies a new set, based on the current state of the interfaces. So it is theoretically possible to get 'no route to host' conditions during the restart if a route cache entry expires at exactly the right time. -Tom -- Tom Eastep \ When I die, I want to go like my Grandfather who Shoreline, \ died peacefully in his sleep.
