Parameters
half-life-reachable: Half-life for reachable routes in minutes. By default, the value is 15
minutes.
half-life-unreachable: Half-life for unreachable routes in minutes. By default, the value
is 15 minutes.
reuse: Reuse threshold value for suppressed routes. A suppressed route whose
penalty value decreases under the value is reused. By default, the reuse value is 750.
suppress: Suppression threshold. The route with a penalty value higher than the
threshold is suppressed. The default value is 2000.
ceiling: Ceiling penalty value, which must be bigger than the suppress value. By default,
the value is 16000.
route-policy-name: Routing policy name.
half-life-reachable, half-life-unreachable, reuse, suppress and ceiling are mutually

accordingly.
