It matches a standard community in the bgp update. The 1 is typically an AS
number and the 80 is some meaningful number that AS 1 tells uses for
matching purposes.

I would hope that if your learning about dampening that you know what
communities are for. If not, I would suggest going back and reading more
about them as they're very important to understand.

Subject: BGP Route dampening - Selective

Hi Group,
 
I had done a lab on route-dampening and found it working fine for a simple
route dampening.
 
We can also selectively dampen the routes by putting a route-map on the bgp
configuration. the configuration says that we have to configure a community
for each selective route dampening.
 
ip community-list 8 permit 1:80
ip community-list 10 permit 1:200
 
route-map damp permit 10
match community 8
set dampening 5 750 2000 10
 
Can anybody tell me what exactly 1:80 or 1:200 is ?

how does this do selective dampening.
 
Cheers
Raj
