 > 4. **Hold down timer** : When a destination has become unreachable (or the metric has increased enough to cause poisoning), the destination goes into "holddown". During this state, no new path will be accepted for the same destination for this amount of time. The hold time indicates how long this state should last. > 4. **Hold down timer** : When a destination has become unreachable (or the metric has increased enough to cause poisoning), the destination goes into "holddown".
