Parameters
half-life-reachable: Specifies the half-life for reachable routes, in the range of 1 to 45 minutes. By default,
the value is 15 minutes.
half-life-unreachable: Specifies the half-life for unreachable routes, in the range of 1 to 45 minutes. By
default, the value is 15 minutes.
reuse: Specifies the reuse threshold value for suppressed routes, in the range of 1 to 20000. A
suppressed route having the penalty value decreased under the value is reused. By default, the value is
750.
suppress: Specifies a threshold in the range of 1 to 20000. A route is suppressed if its penalty value
exceeds this value. The value must be greater than the reuse value. By default, the value is 2000.
ceiling: Specifies a ceiling penalty value in the range of 1001 to 20000. The value must be greater than
the suppress value. The default is 16000.
route-policy-name: Specifies a routing policy by its 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 accordingly.
