Parameters
half-life-reachable: Half-life for reachable routes, in the range of 1 to 45 minutes. By default, the value is
15 m i n u t e s .
half-life-unreachable: Half-life for unreachable routes, in the range of 1 to 45 minutes. By default, the
value is 15 minutes.
reuse: Reuse threshold value for suppressed routes, in the range of 1 to 20000. Penalty value of a
suppressed route decreasing under the value is reused. By default, its value is 750.
suppress: Suppression threshold from 1 to 20000, which should be bigger than the reuse value. Routes
with a penalty value bigger than the threshold are suppressed. By default, it is 2000.
ceiling: Ceiling penalty value from 1001 to 20000. The value must be bigger than the suppress value.
By default, the value is 16000.
route-policy-name: Routing policy name, a 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.
