Thank you Greg, and Derek.

Rack8R6#sh ip bgp dampening parameters
 dampening 15 750 2000 60 (route-map DAMPMAP 10)
  Half-life time : 15 mins Decay Time : 2320 secs
  Max suppress penalty: 12000 Max suppress time: 60 mins
  Suppress penalty : 2000 Reuse penalty : 750

You were right!

Another way than setting the params in the route map is just using the
default command in bgp config mode, "bgp dampening". (in case the task said
not to set the params in the route map, etc.)

Did a quick cut and paste config into dynamips and got the same error
message. I think you just need to configure the dampening parameters to
finish up.

Rack1R1#sh ip bgp dampening
*Mar 1 00:01:19.919: %BGP-3-BADROUTEMAP: Bad parameters in the route-map
DAMPMAP applied for Dampening
Rack1R1#sh ip bgp dampening

ROM: ROMMON Emulation Microcode
ROM: 3600 Software (C3640-JK9S-M), Version 12.4(12), RELEASE SOFTWARE (fc1)

Rack1R1(config)#route-map DAMPMAP 10
Rack1R1(config-route-map)#set
Rack1R1(config-route-map)#set dam
Rack1R1(config-route-map)#set dampening ?
  <1-45> half-life time for the penalty

Rack1R1(config-route-map)#set dampening ?
  <1-45> half-life time for the penalty

Rack1R1(config-route-map)#set dampening
% Incomplete command.

I think you need to configure the damping parameters for it to work.
