The following example shows a route map with multiple instances. The show config command displays only the configuration of the current route map instance. To view all instances of a specific route map, use the show route-map command. Dell#show route-map dilling route-map dilling, permit, sequence 10 Match clauses: Set clauses: route-map dilling, permit, sequence 15 Match clauses: interface Loopback 23 Set clauses: tag 3444 Dell# To delete a route map, use the no route-map map-name command in CONFIGURATION mode. Configure Route Map Filters Within ROUTE-MAP mode, there are match and set commands. • match commands search for a certain criterion in the routes. • set commands change the characteristics of routes, either adding something or specifying a level. When there are multiple match commands with the same parameter under one instance of route-map, the system does a match between all of those match commands. If there are multiple match commands with different parameters, the system does a match ONLY if there is a match among ALL the match commands. In the following example, there is a match if a route has any of the tag values specified in the match commands. Example of the match Command to Match Any of Several Values Dell(conf)#route-map force permit 10 Dell(config-route-map)#match tag 1000 Dell(config-route-map)#match tag 2000 Dell(config-route-map)#match tag 3000 In the next example, there is a match only if a route has both of the specified characteristics. In this example, there a match only if the route has a tag value of 1000 and a metric value of 2000. Also, if there are different instances of the same route-map, then it's sufficient if a permit match happens in any instance of that route-map. Example of the match Command to Match All Specified Values Dell(conf)#route-map force permit 10 Dell(config-route-map)#match tag 1000 Dell(config-route-map)#match metric 2000 In the following example, instance 10 permits the route having a tag value of 1000 and instances 20 and 30 deny the route having a tag value of 1000. In this scenario, the system scans all the instances of the route-map for any permit statement. If there is a match anywhere, the route is permitted. However, other instances of the route-map deny it. Example of the match Command to Permit and Deny Routes Dell(conf)#route-map force permit 10 Dell(config-route-map)#match tag 1000 Dell(conf)#route-map force deny 20 Dell(config-route-map)#match tag 1000 Dell(conf)#route-map force deny 30 Dell(config-route-map)#match tag 1000 Access Control Lists (ACLs) 132
