Remarks that do not have a corresponding rule are incremented as a rule. These two mechanisms allow
remarks to retain their original position in the list. The following example shows remark 10 corresponding
to rule 10 and as such, they have the same number before and after the command is entered. Remark 4 is
incremented as a rule, and all rules have retained their original positions.

Route Maps
Similar to ACLs and prefix lists, route maps are composed of a series of commands that contain a
matching criterion and an action; however, 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.
