match as-path
Adds autonomous system path to the matching clauses of the specified route map.
Syntax: match as-path list-name [list-name...]
no match as-path [list-name...]
list-name
Name of a defined autonomous system path based access list. Case is significant.
Description: Use the ip as-path access-list command to create an access list based on autonomous system paths. Use the show ip access-lists command to display the names of all defined as-path access lists.
Use the match as-path command to configure the route map to test whether the route's autonomous system path matches autonomous system paths in the specified as-path access-list. Routes without a matching autonomous system path are ignored.
Use the no match as-path command to delete a as-path access list matching clause from the route map.
Use the route-map command to create a route map. Use the various match and set commands to define the conditions for redistributing routes between protocols.
Route maps consist of sets of match and set commands. Match commands define the match criteria for route maps. Routes that match all defined match criteria are processed according to the actions defined by the set commands. Routes that do not match all of the defined match criteria in the route map are ignored.
Factory Default: No path lists defined.
Command Mode: Route map configuration.
Example: In the following example:
- The ip as-path access-list command creates an as-path based access list named 40.
- The route-map command creates a route map named match40.
- The match as-path command adds a match clause to the route map to match routes permitted by the access list named 40.
Routes that match entries in as-path access list 40 are processed according to any set commands in the route map. Routes without a matching autonomous system path are ignored.
router(config)#ip as-path access-list 40 permit _411_
router(config)#ip as-path access-list 40 permit ^401$
router(config)#ip as-path access-list 40 deny .*
router(config)#route-map match40 permit 10
router(config-route-map)#match as-path 40
router(config-route-map)#end
router(config)#
