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..
