set tag
Sets the route tag value.
Syntax: set tag tag-value
no set tag
tag-value
Valid values are integers between 1 and 4294967295.
Description: Use the set tag command to define tag value of the destination routing protocol when a criteria (defined by the match tag command) in the route map is matched.
Use the no set tag command to delete the entry in the route map.
Route maps consist of sets of match and set commands. Match commands define the match criteria for route maps. Routes that match one or more match criteria are processed according to the actions defined by the set commands. Routes that do not match at least one of the match criteria in the route map are ignored.
Use the route-map command to create a route map. Use the various match (to define match criteria) and set commands (to define the actions taken if a match is made) to define the conditions for redistributing routes between protocols or between instances of the same protocol.
Route tags are used to communicate information between autonomous system boundary routers. OSPF supports tags. Other protocols have a tag of zero. You can select the source of exported routes based on tags. This is useful when routes classified by tag are exported into a given routing protocol.
Factory Default: If not defined using the set tag command, the default is to forward the tag (if any) from in the source routing protocol to the destination protocol.
Command Mode: Route map configuration.
Example: In the following example:
- The route-map command creates a route map named set-tag.
- The match as-path command adds a match clause to the route map to match routes that appear in as-path access list 3 (not shown here).
- The set tag command specifies routes that match access list 3 are redistributed with a tag of 5.
router(config)#route-map set-tag permit 10
router(config-route-map)#match as-path 3
router(config-route-map)#set tag 5
router(config-route-map)#end
router(config)#
