timers spf (OSPFv3)
Enables shortest path rst (SPF) throttling to delay an SPF calculation when a topology change occurs.
Syntax
timers spf [start-time [hold-time [max-wait]]]
Parameters
• start-time — Sets the initial SPF delay in milliseconds (1 to 600000; default 1000).
• hold-time — Sets the additional hold time between two SPF calculations in milliseconds (1 to 600000;
default 10000).
• max-wait — Sets the maximum wait time between two SPF calculations in milliseconds (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 specied start time. When the start timer nishes, 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 is delayed for double the congured hold time up to
maximum wait time.
