network convergence, not throttling can result in a network not functioning as
expected. If network topology is unstable, throttling slows down the scheduling of
route calculations until the topology regains its stability.
The first route calculation is controlled by the initial wait interval and the second
calculation is controlled by the second wait interval. Each subsequent wait interval is
twice as long as the previous one until the wait interval reaches the maximum wait time
specified (interval seconds). After the network calms down and there are no
triggers for two times the maximum interval, fast behavior is restored (the initial wait
time).
