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
