Configure options for running the shortest-path-first (SPF) algorithm. You can configure
a delay for when to run the SPF algorithm after a network topology change is detected,
the maximum number of times the SPF algorithm can run in succession, and a hold-down
interval after the SPF algorithm runs the maximum number of times.
—Time interval between the detection of a topology change and when
delay milliseconds
the SPF algorithm runs.
Range: 50 through 8000 milliseconds
Default: 200 milliseconds
holddown milliseconds —Time interval to hold down, or wait before a subsequent SPF
algorithm runs after the SPF algorithm has run the configured maximum number of
times in succession.
Range: 2000 through 20,000 milliseconds
