set community
Use this command to set the communities attribute. and group destinations in a certain community, as well as apply routing decisions according to those communities.
To use this command, you must first have a match clause. Match and set commands set the conditions for redistributing routes from one routing protocol to another. The match command specifies the match criteria under which redistribution is allowed for the current route-map. The set command specifies the set redistribution actions to be performed, if the match criteria are met.
If the packets do not match any of the defined criteria, they are routed through the normal routing process.
Use the no parameter with this command to delete the entry.
