Syntax Parameters timers spf [start-time [hold-time [max-wait]]] • start-time - Sets the initial SPF delay in milliseconds, from 1 to 600000; default 1000. • hold-time - Sets the additional hold time between two SPF calculations in milliseconds, from 1 to 600000; default 10000. • max-wait - Sets the maximum wait time between two SPF calculations in milliseconds, from 1 to 600000; default 10000. Default • start-time - 1000 milliseconds • hold-time - 10000 milliseconds • max-wait - 10000 milliseconds Command Mode ROUTER-OSPFv3 Usage Information OSPFv2 and OSPFv3 support SPF throttling. By default, SPF timers are disabled in an OSPF instance. Use SPF throttling to delay SPF calculations during periods of network instability. In an OSPF network, a topology change event triggers an SPF calculation after a specified start time. When the start timer finishes, a hold time may delay the next SPF calculation for an additional time. When the hold timer is running: • Each time a topology change occurs, the SPF calculation delays for double the configured hold time up to maximum wait time. • If no topology change occur, an SPF calculation performs and the hold timer resets to its configured value.
