IP Routing Policy Configuration Commands 237
■ Use the undo if-match community command to cancel the configuration of
the matched community list number.
One of the match sub-statements of route-policy is used to filter BGP routing
information. The match condition is specified according to the community
attributes of the routing information.
Related command: route-policy, ip community-list.
Example
A community-list numbered as 1 is defined first, allowing the autonomous system
number to contain the routing information of 100 and 200. Then, the route-policy
named test is defined. The node No.10 of the route-policy defines a match
sub-statement, which quotes the definition of the community-list.
[SW7700]ip community-list 1 permit 100:200
[SW7700]route-policy test permit node 10
