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
Conguring Match Routes
To congure 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 specic 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.
• For a VLAN, enter the keyword vlan then a number from 1 to 4094.
• Match destination routes specied in a prex list (IPv4).
CONFIG-ROUTE-MAP mode
match ip address prefix-list-name
• Match destination routes specied in a prex list (IPv6).
CONFIG-ROUTE-MAP mode
match ipv6 address prefix-list-name
• Match next-hop routes specied in a prex list (IPv4).
CONFIG-ROUTE-MAP mode
match ip next-hop {access-list-name | prefix-list prefix-list-name}
• Match next-hop routes specied in a prex list (IPv6).
CONFIG-ROUTE-MAP mode
match ipv6 next-hop {access-list-name | prefix-list prefix-list-name}
