We are trying to set up a policy for the restart and reload of Proteon
Routers on our 80Mb ring.  All 10 of the P4200s are running 8.2 software
with the new ROMs.  The main idea is to maintain connections through
the routers when doing restarts and reloads or not notify eveyone
affected of our intention to restart/reload.

Through experimentation we have found that restarts do not affect
connections.  Is this always the case and should we feel free to restart
a router without notification, knowing connections will not be dropped?

For the most part, reloads, even with the new ROMs, do no affect connections.
Some connections have dropped in the past, however, when we reload a
router.  Certainly the network software being run on individual hosts will
affect the robust-ness of the connection.  When does a P4200 determine that
a host/net is unreachable?  Should we reload only after everyone on the
net has been notified?
