BGP dampening for specific nets

I want to be able to dampen a specific set of flapping routes in my bgp table using a different set of parameters from my default dampening.

From the IOS docs, it looks like the following would work:

*****

ip access-list standard dampen-routes

permit 140.10.4.0 0.0.0.255

!

!

route-map dampen permit 10

match ip address dampen-routes

set dampening 15 800 1000 15

router bgp 100

neighbor 192.168.1.2 route-map dampen in

*****

However, when the route-map is applied to the neighbor, the following message is generated

% "dampen" used as BGP inbound route-map, set dampening not supported

This is a 3620 IOS 12.2(15)T14. Should this work, or is there another way to set dampening on specific prefixes?

thx

The route-map should be applied using the following command, not with an inbound route-map.

bgp dampening route-map dampen

Hope this helps,

Thanks, works great got thrown off by the documentation under "set dampening" in the Router Command Reference, which shows it in a route-map on a neighbor statement. Should have check the bgp dampening command...

Thanks
