Use the set form of this command to define a match condition for a route map policy based on an AS path list.
Packets are matched based on whether the AS path listed in the route match the AS path 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 AS path match condition.
Use the show form of this command to display AS path match condition configuration.
