match tag tag-value [...tag-value]
no match tag tag-value [...tag-value]
tag-value List of one or more route tag values. Each can be an integer from 0 to 4294967295.
To redistribute routes in the routing table that match the specified tags, use the match tag command in route-map configuration mode. To remove the tag entry, use the no form of this command.
Use the route-map global configuration command, and the match and set route-map configuration commands, to define the conditions for redistributing routes from one routing protocol into another. Each route-map command has a list of match and set commands associated with it. The match commands specify the match criteria--the conditions under which redistribution is allowed for the current route-map command. The set commands specify the set actions--the particular redistribution actions to perform if the criteria enforced by the match commands are met. The no route-map command deletes the route map.
The match route-map configuration command has multiple formats. The match commands can be given in any order, and all match commands must "pass" to cause the route to be redistributed according to the set actions given with the set commands. The no forms of the match commands remove the specified match criteria.
A route map can have several parts. Any route that does not match at least one match clause relating to a route-map command will be ignored; that is, the route will not be advertised for outbound route maps and will not be accepted for inbound route maps. If you want to modify only some data, you must configure second route map section with an explicit match specified.
The following example distributes routes that have been advertised by routers and access servers at the addresses specified by previously defined access lists:Router(config)#route-map name Router(config)#match tag 5
match ip address
match ip next-hop
set metric BGP OSPF RIP
