Use the set as-path command to specify an autonomous system path. By specifying the length
of the AS-Path, the router influences the best path selection by a neighbor. Use the prepend
parameter with this command to prepend an AS path string to routes increasing the AS path
length.
To use the set as-path command, you must first have a match clause. Match and set commands
set the conditions for redistributing routes from one routing protocol to another. The match
command specifies the match criteria under which redistribution is allowed for the current
route-map. The set command specifies the set redistribution actions to be performed, if the
match criteria are met.
If the packets do not match any of the defined criteria, they are routed through the normal
routing process.
Note:
This command is valid for BGP only.
