Release Information

Statement introduced in JUNOS Release 8.5.

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.
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.
rapid-runs number—Maximum number of times the SPF algorithm can run in succession. After the maximum is reached, the holddown interval begins.

Usage Guidelines

See Configuring SPF Options for IS-IS.
