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 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport] information.
    • For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
    • For a Loopback interface, enter the keyword loopback then a number from 0 to 16383.
    • For a port channel interface, enter the keywords port-channel then a number.
    • For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
  • Match destination routes specified in a prefix list (IPv4).
    CONFIG-ROUTE-MAP mode
    match ip address prefix-list-name
  • Match destination routes specified in a prefix list (IPv6).
    CONFIG-ROUTE-MAP mode
    match ipv6 address prefix-list-name
  • Match next-hop routes specified in a prefix list (IPv4).
    CONFIG-ROUTE-MAP mode
    match ip next-hop {access-list-name | prefix-list prefix-list-name}
  • Match next-hop routes specified in a prefix list (IPv6).
    CONFIG-ROUTE-MAP mode
    match ipv6 next-hop {access-list-name | prefix-list prefix-list-name}
  • Match source routes specified in a prefix list (IPv4).
    CONFIG-ROUTE-MAP mode
    match ip route-source {access-list-name | prefix-list prefix-list-name}
  • Match source routes specified in a prefix list (IPv6).
    CONFIG-ROUTE-MAP mode
    match ipv6 route-source {access-list-name | prefix-list prefix-list-name}
  • Match routes with a specific value.
    CONFIG-ROUTE-MAP mode
    match metric metric-value
  • Match BGP routes based on the ORIGIN attribute.
    CONFIG-ROUTE-MAP mode
    match origin {egp | igp | incomplete}
  • Match routes specified as internal or external to OSPF, ISIS level-1, ISIS level-2, or locally generated.
    CONFIG-ROUTE-MAP mode
    match route-type {external [type-1 | type-2] | internal | level-1 | level-2 | local }
  • Match routes with a specific tag.
    CONFIG-ROUTE-MAP mode
    match tag tag-value

To create route map instances, use these commands. There is no limit to the number of match commands per route map, but the convention is to keep the number of match filters in a route map low. Set commands do not require a corresponding match command.
