the delay in transmitting LSAs on the interface. By adjusting the SPF calculation interval, you
can mitigate resource consumption due to frequent network changes.
You can specify the DR priority of an interface to affect the DR/BDR election in a broadcast
network.

6.8.2 Configuring the SPF Timer

By setting the interval for SPF calculation, you can reduce resource consumption caused by
frequent network changes.
Context
Whenever the LSDB of OSPFv3 changes, the shortest path should be recalculated. Calculating
the shortest path each time the LSDB changes consumes enormous resources and lowers the
efficiency of a router.
Adjusting the SPF delay and hold interval can suppress frequent network changes to avoid
resource consumption.
