Filtering
NOTE
By default, route maps apply to both unicast and multicast traffic.
The route-type internal | external-type1 | external-type2 parameter applies only to OSPF routes.
This parameter compares the route type to the specified value.
The tag tag-value parameter compares the route tag to the specified value.
Match examples using ACLs
The following sections show some detailed 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.
Brocade(config)#route-map PathMap permit 1
Brocade(config-routemap PathMap)#match as-path 1
Syntax: match as-path num
The num parameter specifies an AS-path ACL and can be a number from 1 through 199. You can
specify up to five AS-path ACLs. To configure an AS-path ACL, use the ip as-path access-list
command. Refer to
“Defining an AS-path ACL” on page 335.
Matching based on community ACL
To construct a route map that matches based on community ACL 1, enter the following commands.
Brocade(config)#ip community-list 1 permit 123:2
Brocade(config)#route-map CommMap permit 1
Brocade(config-routemap CommMap)#match community 1
Syntax: match community string
The string parameter specifies a community list ACL. To configure a community list ACL, use the ip
community-list command. Refer to
“Defining a community ACL” on page 339.
Matching based on destination network
To construct match statements for a route map that match based on destination network, use the
following method. You can use the results of an IP ACL or an IP prefix list as the match condition.
Brocade(config)#route-map NetMap permit 1
Brocade(config-routemap NetMap)#match ip address 1
Syntax: match ip address name-or-num
Syntax: match ip address prefix-list name
The name-or-num parameter with the first command specifies an IP ACL and can be a number from
1 through 199 or the ACL name if it is a named ACL. To configure an IP ACL, use the ip access-list or
access-list command. Refer to the chapter “Rule-Based IP ACLs” in the Brocade ICX 6650 Security
Configuration Guide.
The name parameter with the second command specifies an IP prefix list name. To configure an IP
prefix list, refer to
“Defining IP prefix lists” on page 340.
