configure policy community_list

Router User Guide
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.
