Hold Interval field: Specifies the amount of time, in seconds, that a route remains in a hold down state. The interval should be several times the value in the Update Interval field. The interval must be at least as long as the flush interval minus the invalid interval. This field displays only when the Use protocol defaults field is set to off. When a route has become unreachable (or the metric has increased enough to cause poisoning), the route goes into a hold down state (when the Holddown field is enabled). During this state, no new route will be accepted for the same destination for this amount of time.
Range: 1-65535
Default: 3 times the value in the Update Interval field + 10.
