Description

A route map is a very flexible mechanism for specifying what to do with routes. A route map lets you match certain routes and set various parameters of the matching routes. The route-map command merely defines the list; the match command specifies which routes the map should match (something like an access list); and a number of set commands specify what to do with the matching routes.

A route map is identified by a name (tag-name); any number of route-map commands can share the same name. route-map commands with the same name are processed in the order given by the sequence-number. Although most route processing is specified by the set commands associated with the map, the permit and deny keywords can be used to specify some very simple processing. permit is the default; it means that normal route processing (as specified by the set commands) takes place for all routes that match the map.

Processing continues with other route maps that share the same sequence number. The deny keyword specifies that if a match occurs, the route is not distributed and no further processing of other route maps takes place.

To delete a route map, use the no form of the command. Note that if you omit the sequence-number, this command deletes all maps matching the given tag-name.
