When RIPng detects a route with a high metric associated, the router waits for a period of time before making any updates into the routing table. This minimises the effects of route flapping to the routing table. The period of time that RIPng waits is the hold-down timer.

To configure the hold-down timer for RIPng, include the holddown statement, which can be a value from 10 through 180. The default value is 180 seconds.

Graceful restart is disabled by default. You can globally enable graceful restart for all routing protocols under the [edit routing-options] hierarchy level.

You can configure graceful restart parameters specifically for RIPng. To do this, include the graceful-restart statement.

To disable graceful restart for RIPng, specify the disable statement. To configure a time period for the restart to finish, specify the restart-time statement.
