Configuration mode


policy {
    route {
        extcommunity-list {
                standard [list-num | list-name ]
                expanded [list-num | list-name ]
                    {
                         rule rule-num {
                            action {
                                deny
                                permit
                                }
                         }    
                    } 
              }
       }
}

Use the set form of this command to define the action to specify the action to take when packets match an extended community list rule.

If the action for a rule is deny, packets that match the criteria of the rule are silently dropped. If the action for the rule is permit, destination-based routing is performed; that is, packets are sent by using the normal forwarding channels.

Use the delete form of this command to restore the default action to take for packets that match the criteria for a rule.

Use the show form of this command to display the action to take for a rule.
