Version Description7.8.1.0 Introduced on all platforms.Usage Information The higher this parameter is set, the faster OSPF converge takes place.NOTE: The faster the convergence, the more frequent the route calculations andupdates. This behavior impacts CPU utilization and may impact adjacencystability in larger topologies.Generally, convergence level 1 meets most convergence requirements. Higherconvergence levels should only be selected following consultation with DellNetworking technical support.graceful-restart grace-periodSpecifies the time duration, in seconds, that the router’s neighbors continue to advertise the router as fullyadjacent regardless of the synchronization state during a graceful restart.C9000 SeriesSyntax graceful-restart grace-period secondsTo disable the grace period, use the no graceful-restart grace-periodcommand.Parameters seconds Time duration, in seconds, that specifies the duration of therestart process before OSPF terminates the process. The range isfrom 40 to 1800 seconds.Defaults Not ConfiguredCommand Modes ROUTER OSPFCommand History This guide is platform-specific.
