There is a big difference between dropping a link and readdressing an 
endpoint.  The former may cause a minor interruption in traffic flow, 
which may then resume if the outage is short enough/timers long 
enough.  The latter is guaranteed to break all existing sessions, 
requiring the user to reconnect, reauthenticate, etc.
