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
Configuring Match Routes
To configure match criterion for a route map, use the following commands.
•
Match routes with the same AS-PATH numbers.
CONFIG-ROUTE-MAP mode
match as-path as-path-name
•
Match routes with COMMUNITY list attributes in their path.
CONFIG-ROUTE-MAP mode
match community community-list-name [exact]
•
Match routes whose next hop is a specific interface.
CONFIG-ROUTE-MAP mode
match interface interface
The parameters are:
•
For a loopback interface, enter the keyword loopback then a number between zero (0) and 16383.
•
For a port channel interface, enter the keywords port-channel then a number.
•
For a 10-Gigabit Ethernet interface, enter the keyword tengigabitEthernet then the slot/port
information.
•
For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
