Creating a Route Map Route maps, ACLs, and prefix lists are similar in composition because all three contain filters, but route map filters do not contain the permit and deny actions found in ACLs and prefix lists. Route map filters match certain routes and set or specify values. To create a route map, use the following command. • Create a route map and assign it a unique name. The optional permit and deny keywords are the action of the route map. CONFIGURATION mode route-map map-name [permit | deny] [sequence-number] The default is permit. The optional seq keyword allows you to assign a sequence number to the route map instance. Examples of Working with Route Maps The default action is permit and the default sequence number starts at 10. When you use the keyword deny in configuring a route map, routes that meet the match filters are not redistributed. To view the configuration, use the show config command in ROUTE-MAP mode. The following example shows viewing a configured route-map. Dell(config-route-map)#show config ! route-map dilling permit 10 Dell(config-route-map)# You can create multiple instances of this route map by using the sequence number option to place the route maps in the correct order. The system processes the route maps with the lowest sequence number first. When a configured route map is applied to a command, such as redistribute, traffic passes through all instances of that route map until a match is found. The following is an example with two instances of a route map. Dell#show route-map route-map zakho, permit, sequence 10 Match clauses: Set clauses: route-map zakho, permit, sequence 20 Match clauses: interface TengigabitEthernet 0/1 Set clauses: tag 35 level stub-area Dell# To delete all instances of that route map, use the no route-map map-name command. To delete just one instance, add the sequence number to the command syntax. Dell(conf)#no route-map zakho 10 Dell(conf)#end Dell#show route-map route-map zakho, permit, sequence 20 Match clauses: interface TengigabitEthernet 0/1 Set clauses: tag 35 level stub-area Dell# Access Control Lists (ACLs) 131
