policy {
    route-map map-name {
        rule rule-num {
            match {
                extcommunity {
                    extcommunity-list list-num
                    exact-match

Use the set form of this command to define a match condition for a route map policy based on BGP extended communities.

Packets are matched based on whether the BGP communities listed in the route match the communities defined by this command. Depending on the action defined for the rule using policy route route-map <map-name> rule <rule-num> action, matched packets are either permitted or denied. Based on the forwarding information specified by the set statements in the route map rule, permitted packets are forwarded to their various destinations.

If more than one match condition is defined in a route map rule, the packet must match all conditions to count as a match. If no match condition is defined for the route map rule, all packets are considered to match the rule.

Use the delete form of this command to remove the BGP extended community match condition.

Use the show form of this command to display BGP extended community match condition configuration.
