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,
Dell Networking OS does a match between all of those match commands. If there are multiple match
commands with different parameters, Dell Networking OS 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
The following example shows using 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
Example of the match Command to Match All Specified Values
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.
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, Dell Networking OS 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
