[c-nsp] OSPF question

[Tony Baade]

We experienced an issue on our network where we have a link between 2 cisco ME6524s.  There was packet loss across the link, but the interfaces on either side never actually dropped.  The packet loss however was severe enough to cause problems w/ our OSPF (the neighbor session kept dropping up and down) and as a result this caused our iBGP hellos to timeout, causing an outage affecting several routers.

My question is there some way to dampen a flapping neighbor in OSPF?  So if the interface doesn't actually go down, but there is X amount of packet loss in Y amount of time (or if the neighbor goes up and down a certain number of times) the switch will recognize this issue and stop using that link? We are already using IP Event Dampening, which didn't kick in because the interfaces never actually went down.

If there's no way in OSPF to do this, is there support for this in another IGP, or is there any other workaround for this kind of situation?

Any advice is appreciated, thanks in advance,
