configure policy community_list
This command accesses next-level commands for adding extended or standard community lists.
Community lists are used for matching the “community” attribute in a BGP route. A community list succeeds if any
“permit” line in the list matches, or fails if any “deny” line matches. Matching proceeds sequentially and stops at
the first match. A line in a community list is normally said to match if the route being tested contains at least all of
the communities listed in the line. That is, it may contain additional communities as well. If the exact-match
keyword is used, then it must contai8n exactly the same communities as listed.
The communities parameter can be:
• local_as
• no_advertise
• no_export
• aa:nn (an integer between 0 and 65,535)
• community (an integer between 1 and 4294967295
Note that “exact_match” is supported in the community_list as well as at the route_map level. If neither permit nor
deny is specified, the default is permit. If no community is specified, any route will be matched, regardless of what
communities are present. The route will even be matched if the community path attribute is not present. Any
number of community list lines may be declared. They are evaluated in the order declared.
