match community
Adds this BGP community list to the matching clauses of the route map.
Syntax: match community list-name [list-name ...][exact-match]
no match community [list-name]
list-name
Name of a community list.
exact-match
An exact match of the community identifiers in the community list is required.
Description: Use the ip community-list command to create BGP community lists.
Use the match community command to create an entry in a route map to test whether the route is a member of the community specified in the BGP community list.
A community list can include identifiers for several communities.
Use the match community listname syntax to match on one or more community identifiers in a community list. Use the exact match keyword to exactly match all the communities in a community list.
Use the show ip bgp community-list command to display defined community lists
Use the no match community command to delete a community list entry.
Route maps consist of sets of match and set commands. Match commands define the match criteria for route maps. Routes that match all defined match criteria are processed according to the actions defined by the set commands. Routes that do not match all of the defined match criteria in the route map are ignored.
Communities are groups of destinations that share the community attribute. You can group destinations into communities and then apply routing decisions based on the communities.
Use the route-map command to create a route map. Use the various match and set commands to define the conditions for redistributing routes between protocols.
Factory Default: No community lists are defined.
Command Mode: Route map configuration.
Example: In the following example:
- The ip community-list command creates a community list named 12 to permit all routes from community 109.
- The route-map command creates a route map named setweight10.
- The match community command adds a match clause to the route map to match routes permitted by community list 12.
router(config)#ip community-list 12 permit 109
router(config)#route-map setweight10 permit 10
router(config-route-map)#match community 12
router(config-route-map)#set weight 10
router(config-route-map)#end
router(config)#
Routes that match entries in community-list 12 have their weight set to 10.
