NETGEAR 8800 Chassis Switch CLI Manual Default The default is none. Usage Guidelines This command configures the router as a graceful OSPF router. When configured for planned restarts, it will advertise Grace-LSAs before restarting (for example, during an upgrade of the OSPF module). When configured for unplanned restarts, it will advertise Grace-LSAs after restarting but before sending any Hellos. When configured for both, the router will advertise restarting regardless of whether the restart was planned or unplanned. Example The following command configures a router to perform graceful OSPF restarts only for planned restarts: configure ospf restart planned configure ospf restart grace-period configure ospf restart grace-period Description Configures the grace period sent out in Grace-LSAs and used by a restarting router. Syntax Description seconds Grace period, in seconds. The default value is 120 seconds. Range is 1 to 1800 seconds. Default The default is 120 seconds. Usage Guidelines This command configures the grace period sent out to helper neighbor routers and used by the restarting router. The value of the grace period must be greater that the dead interval, and less than the LSA refresh time. Example The following command configures a router to send LSAs with a 240 second grace period during graceful OSPF restarts: configure ospf restart grace-period 240 1012 | Chapter 23. OSPF Commands
