Specifying the match conditions
Use the following command to define the match conditions for instance 1 of the route map GET_ONE. This instance compares the route
updates against BGP4 address filter 11.
device(config-routemap GET_ONE)# match address-filters 11
Syntax: [no] match [ as-path name ] [ community acl exact-match ] | [ ip address acl | prfix-list string ] | [ ip route-source acl | prefix
name ] [ metric num ] | [ next-hop address-filter-list ] | [ route-type internal | external-type1 | external-type2 ] [ tag tag-value ] |
interface interface interface interface .. protocol bgp static-networkprotocol bgp externalprotocol bgp internal
The as-path num parameter specifies an AS-path ACL. You can specify up to five AS-path ACLs. To configure an AS-path ACL, use the
ip as-path access-list command.
The community num parameter specifies a community ACL.
NOTE
The ACL must already be
configured.
The community acl exact-match parameter matches a route if (and only if) the route community attributes field contains the same
community numbers specified in the match statement.
The ip address, next-hop acl-num , prefix-list, and string parameters specify an ACL or IP prefix list. Use this parameter to match based
on the destination network or next-hop gateway. To configure an IP ACL for use with this command, use the ip access-list command. To
configure an IP prefix list, use the ip prefix-list command.
The ip route-source acl and prefix name parameters match based on the source of a route (the IP address of the neighbor from which
the device learned the route).
The metric num parameter compares the route MED (metric) to the specified value.
The next-hop address-filter-list parameter compares the IP address of the route next-hop to the specified IP address filters. The filters
must already be configured.
The route-type internal, external-type1, and external-type2 parameters apply only to OSPF routes. These parameters compare the
route type to the specified value.
The tag tag-value parameter compares the route tag to the specified tag value.
The protocol bgp static-network parameter matches on BGP4 static network routes.
The protocol bgp external parameter matches on eBGP (external) routes.
The protocol bgp internal parameter matches on iBGP (internal) routes.
Match examples using ACLs
The following sections contain examples of how to configure route maps that include match statements that match on ACLs.
Matching based on AS-path ACL
To construct a route map that matches based on AS-path ACL 1, enter the following commands.
device(config)# route-map PathMap permit 1
device(config-routemap PathMap)# match as-path 1
Syntax: [no] match as-path string
The string parameter specifies an AS-path ACL and can be a number from 1 through 199. You can specify up to five AS-path ACLs.
