Hello!
Well it has to be handled with somewhat caution too... Just a little link-flap
can cause massive network/routing changes.
If you run a routing protocol BGP, OSPF etc it has it's own mechanism with
timers for declaring neighbours/link partners down. But yes in some setups it
can be useful -- with dampning.
