Statement introduced before Junos OS Release 10.2 for J-EX Series switches.
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 holddown
interval after 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 1000 milliseconds
Default: 200 milliseconds
—Time interval to hold down, or wait before a subsequent SPF
holddown milliseconds
algorithm runs after the SPF algorithm has run the configured maximum number of
times in succession.
Range: 2000 through 10,000 milliseconds
Default: 5000 milliseconds
rapid-runs number —Maximum number of times the SPF algorithm can run in succession.
After the maximum is reached, the holddown interval begins.
Range: 1 through 5
Default: 3
