Hierarchy Level

Release Information

Statement introduced before Junos OS Release 7.4.

Description

Enable graceful restart on the router. You must configure the graceful-restart statement at the [edit routing-options] hierarchy level to enable graceful restart on the router.

Options

disable—Disable graceful restart on the router or for RSVP.

helper-disable—Disable RSVP graceful restart helper mode (this option is only available at the [edit protocols rsvp] hierarchy level).

Default: Helper mode is enabled by default.

maximum-helper-recovery-time seconds—The maximum length of time the router stores the state of neighboring routers when they undergo a graceful restart. The value applies to all neighboring routers, so it should be based on the time that the slowest RSVP neighbor requires for restart.

Default: 180 seconds

Range: 1 through 3600 seconds

maximum-helper-restart-time seconds—The maximum length of time the router waits between when it discovers that a neighboring router has gone down and when it declares the neighbor down. This value is applied to all neighboring routers, so it should be based on the time that the slowest RSVP neighbor requires for restart.

Default: 20 seconds

Range: 1 through 1800 seconds

Required Privilege Level

routing—To view this statement in the configuration.
