Description
Use the
if-match community
command to match community attributes of BGP
routing information.
Use the
undo if-match community

matching settings.
Be default, community attributes are not set for matching.
An if-match statement of Route-policy sets community attributes as matching
conditions to filter BGP routing information.
Related command: route-policy and ip community-list.
Example
# Create community-list 1, which permits routing information of AS 100 and AS 200.
Then create a Route-policy named test and define an if-match statement quoting the
definitions of community-list 1 for node 10 of the Route-policy.
