The match as-path command specifies the autonomous system path to be matched. If there is a
match for the specified AS path, and permit is specified, the route is redistributed or controlled,
as specified by the set action. If the match criteria are met, and deny is specified, the route is
not redistributed or controlled. If the match criteria are not met then the route is neither
accepted nor forwarded, irrespective of permit or deny specifications.
The route specified by the policies might not be the same as specified by the routing protocols.
Setting policies enable packets to take different routes, depending on their length or content.
Packet forwarding based on configured policies overrides packet forwarding specified in routing
tables.
Note:
This command is valid only for BGP.
