Use the set form of this command to define a match condition for a route map policy based on the address from where routes are advertised (its route source).
Packets are matched based on whether the route source matches an address contained in the specified access list or prefix list. 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 route source match condition.
Use the show form of this command to display route source match condition configuration.
