問題文
A damping configuration sets a maximum hold down time and leaves the decay half life for the unreachable state unset. A route that has flapped for a long time then goes unreachable and stays that way. What follows from those two settings?
選択肢
- The suppression cannot last longer than the maximum hold down time however unstable the route has been, and while the route stays unreachable its figure of merit does not decay at all.
- The suppression cannot last longer than the maximum hold down time however unstable the route has been, and while the route stays unreachable its figure of merit does decay at the reachable rate after all.
- The suppression is lifted as soon as the route goes unreachable, because there is nothing left to suppress, and the figure of merit is reset to zero at that moment.
- The suppression lasts until the figure of merit falls below the reuse value no matter how long that takes, and while the route stays unreachable its figure of merit does not decay at all.
