![]() If the first topology change event occurs after the maximum wait-interval begins, the SPF calculation is again scheduled at the start-interval and subsequent wait-intervals are reset according to the timers throttle spf command. ![]() ![]() Once the maximum wait-time is reached, the wait-interval remains the same until the topology stabilizes. The wait-interval doubles when at least one topology change event is received during the previous wait-interval. The wait-interval indicates the amount of time to wait before scheduling an SPF calculation in an event of topology change in this case, 1000 milliseconds. Spf-max-wait: Maximum wait between two SPF calculations. Spf-hold: Minimum hold-time between two SPF calculations. Spf-start: Initial delay to schedule an SPF calculation after a topology change. The OSPF SPF Throttling is configured using the command timers throttle spf OSPF router configuration command. ![]() By default, SPF interval is chosen dynamically and depends on frequency of topology changes. SPF runs when there is a topology change. OSPF Shortest Path First Throttling feature allows to schedule SPF calculations in milliseconds interval and delay SPF calculations during network instability.
