28.4.1 List of configuration commands

Configure the OSPFv3 helper functionality on the Switch if you intend to use the OSPFv3 restart functionality on any of its neighboring routers.

When the restart function is used, set OSPFv3 restart time (set by graceful-restart restart-time command) to a value that exceeds the switching time required for the master switch plus LSA learning time.

The following table lists the commands used to configure graceful restart.
