Parameters
half-life-reachable
: Half-life for reachable routes, in the range 1 to 45 minutes. By default, the value is
15 minutes.
half-life-unreachable
: Half-life for unreachable routes, in the range 1 to 45 minutes. By default, the
value is 15 minutes.
reuse
: Reuse threshold value for suppressed routes, in the range 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 19 characters.
half-life-reachable, half-life-unreachable, reuse, suppres
s and
ceiling
are mutually dependent. Once
any one is configured, all the others should also be specified accordingly.
