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.

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
