Default level
2: System level
Parameters
half-life-reachable: Specifies a half-life for active routes, in the range of 1 to 45 minutes. The default value
is 15 minutes.
half-life-unreachable: Specifies a half-life for suppressed routes, in the range of 1 to 45 minutes. The
default value is 15 minutes.
reuse: Specifies a reuse threshold value for suppressed routes, in the range of 1 to 20000. A suppressed
route whose penalty value decreases under the value is reused. By default, the reuse value is 750.
suppress: Specifies a suppression threshold in the range of 1 to 20000. The route with a penalty value
higher than the threshold is suppressed. The default value is 2000.
ceiling: Specifies a ceiling penalty value in the range of 1001 to 20000. The value must be bigger than
the suppress value. The default value is 16000.
route-policy-name: Specifies routing policy name, a case-sensitive string of 1 to 63 characters.
half-life-reachable, half-life-unreachable, reuse, suppress and ceiling are mutually dependent. Once any
one is configured, all the others should also be specified.
