Filtering
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.
Brocade(config-routemap GET_ONE)#match address-filters 11
Syntax: match [as-path num] | [address-filters | as-path-filters | community-filters num,num,..] |
[community num] | [community ACL exact-match] | [ip address ACL | prefix-list string] |
[ip route-source ACL | prefix name] [metric num] | [next-hop address-filter-list] | [nlri
multicast | unicast | multicast unicast] | [route-type internal | external-type1 |
external-type2] | [tag tag-value]
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. Refer to
The address-filters | as-path-filters | community-filters num,num,... parameter specifies a filter or
list of filters to be matched for each route. The router treats the first match as the best match. If a
route does not match any filter in the list, then the router considers the match condition to have
failed. To configure these types of filters, use commands at the BGP configuration level:
•
To configure an address filter, refer to
“Specific IP address filtering”
•
To configure an AS-path filter or AS-path ACL, refer to
•
To configure a community filter or community ACL, refer to
You can enter up to six community names on the same command line.
NOTE
The filters must already be configured.
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's community
attributes field contains the same community numbers specified in the match statement.
The ip address | next-hop ACL-num | prefix-list string parameter specifies 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. Refer to the section “ACL
overview” in the Brocade ICX 6650 Security Configuration Guide. To configure an IP prefix list, use
the ip prefix-list command. Refer to
The ip route-source ACL | prefix name parameter matches based on the source of a route (the IP
address of the neighbor from which the Brocade 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 nlri multicast | unicast | multicast unicast parameter specifies whether you want the route
map to match on multicast routes, unicast routes, or both route types.
