Release Information

Statement introduced in JUNOS Release 8.5.

Statement introduced in JUNOS Release 9.0 for EX Series switches.

Description

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.

Options

delay milliseconds—Time interval between the detection of a topology change and when the SPF algorithm runs.

Range: 50 through 1000 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 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

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
