tmnxOspfSpfSecondWait 1.3.6.1.4.1.6527.3.1.2.36.2.1.32

The value of tmnxOspfSpfSecondWait defines the hold time between the first and second SPF calculation. Subsequent SPF runs will occur at exponentially increasing intervals of the tmnxOspfSpfSecondWait value i.e., if tmnxOspfSpfSecondWait is 1000, then the next SPF triggered by an event during this interval will run after 2000 msec, and the subsequent one at 4000 msec, etc. until it is capped off at tmnxOspfSpfMaxWait value. If this is configured as zero, there will be no exponential backoff. The SPF interval will stay at tmnxOspfSpfMaxWait value until there are no more SPF runs scheduled in that interval. After a full interval without any SPF runs, the SPF interval will drop back to tmnxOspfSpfInitialWait.
