No. BGP flap dampening only works on routes that go up and down
periodically while the BGP session they're learned over stays up. When
the session goes down the dampening info is removed.
But it doesn't matter: you're screwed both ways. If you keep routing
stable you lose packets, if you import the flapping into your routing
protocols those become unstable. You need stable links.
