To modify the communities attribute of matching routes, use the set community command in Route Map Configuration mode. The set community command can be used to assign communities to routes originated through BGP‘s network and redistribute commands, and to set communities on routes received from a specific neighbor or advertised to a specific neighbor. It can also be used to remove all communities from a route.
To remove a subset of the communities on a route, use the command set comm-list delete.
