Administrator Guide

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.

ip access-list extended test
remark 4 XYZ
remark 5 this remark corresponds to permit any host 1.1.1.1

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.
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 Dell Networking OS implementation of route maps allows route maps with the no match or no set
commands. When there is no match command, all traffic matches the route map and the set command
applies.
