Route Maps

Route-maps
Like ACLs and prefix lists, route maps are composed of a series of commands that contain a matching
criterion and an action, yet route maps can change the packets meeting the criterion. ACLs and prefix lists
can only drop or forward the packet or traffic. Route maps process routes for route redistribution. For
example, a route map can be called to filter only specific routes and to add a metric.
Route maps also have an "implicit deny." Unlike ACLs and prefix lists, however, where the packet or
traffic is dropped, in route maps, if a route does not match any of the route map conditions, the route is not
redistributed.

Implementation Information

The FTOS implementation of route maps allows route maps with no match command or no set command.
When there is no match command, all traffic matches the route map and the set command applies.
