Release Information

Statement introduced in JUNOS Release 8.5.

Support for Multitopology Routing introduced in JUNOS Release 9.0.

Support for the realm statement introduced in JUNOS Release 9.2.

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 hold-down interval after the 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 OSPF and Configuring Topologies and SPF Options for MT-OSPF.
