match as-path (Route Map)
Use this command to add an autonomous system (AS) path match clause to a route map
entry. Specify the AS path attribute value or values to match by specifying the name of an
AS path access list. To create the AS path access list, enter Global Configuration mode and
use the ip as-path access-list (BGP and BGP4+) command.
A BGP update message matches the route map if its attributes include AS path values that
match the AS path access list.
Each entry of a route map can only match against one AS path access list in one AS path
match clause. If the route map entry already has an AS path match clause, entering this
command replaces that match clause with the new clause.
Note that AS path access lists and route map entries both specify an action of deny or
permit. The action in the AS path access list determines whether the route map checks
update messages for a given AS path value. The route map action and its set clauses
determine what the route map does with update messages that contain that AS path
value.
Use the no variant of this command to remove the AS path match clause from a route map
entry.
Syntax match as-path <as-path-listname>
no match as-path [<as-path-listname>]
Mode Route-map Configuration
Usage This command is valid for BGP update messages only.
Example To add entry 34 to the route map called myroute, which will discard update messages if
they contain the AS path values that are included in myaccesslist, use the commands:
