Configuration mode


policy {
    route-map map-name {
        rule rule-num {
            set {
                prepend-as {
                   last-as as-count
                   own-as as-count
                 }
             }
        }
    }
}

Use the set form of this command to prepend the last-as or the own-as to the existing as-path of a route. When all the match conditions in the route map rule are met, the last-as or own-as is prepended a specified number of times to the as-path of the route.

Use the delete form of this command to delete the prepend-as configuration from a route map rule.

Use the show form of this command to display the configuration for route maps.

Note: You can configure either the last-as or own-as option under a route map rule but not both.
