Wanted to share that there is a 12.2T option that allows IP dampening in
other routing protocols, not just BGP!!!!

BGP dampening will dampen bgp routes and that is that. It will not
dampen ospf routes. When you redist ospf routes into bgp process, it
does not know how much the ospf route is flapping.
If you have a router behind router B (i.e. a core router) that redists
ospf->bgp and flaps a lot, router B should be able to count penalties
and start dampening it after enough flaps..
