There are restrictions as to which items are allowed
in the route-map for dampening. Things like "match ip
next-hop" or "match ip route-source" are not
supported. AS-Path is supported as a match option.
If you have to be more granular than the dampening
route-map will allow, you can take a two-part approach
and mark the routes inbound from that particular
neighbor with a community and then match on that
community in your route-map.

Not that I've tried it myself, but you could do bgp dampening with the
route map and in the route map before setting the dampening do a match
on IP route-source. Or match any other attributes like say as-path.
Cisco ISP essentials covers it, I believe. I will try it in the lab
tomorrow just in case.

Subject: BGP Dampening per Neigh. basis
Folks,
Is there a way we can dampen BGP routes on a per neighbour basis ? I
did a route map in-bound to a neigh. while setting dampening parameters,
but looks like thats not an option.
Thanks,
-JM
