I do not believe community is a must here. Any match will do. If you match
community, it is a four octet number, which can be represented in different
forms. New way to write community down is AS:NN, where AS is an autonomous
system number and NN is a number within this AS. As far as IOS concerned a
number is a number just now written differently; but it helps ISPs to
administer the community, and when number of ISP peer each one have a
diapason of communities to administer, without having to agree with one
another. As regular expressions can be used to match communities in new
format, which greatly simplifies manipulation.

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
