Configuring SPF throttling timers
SPF calculation is throttled with default timer values (start-time 200ms, hold-time 1000ms, max-wait-time 5000ms). You can throttle SPF calculation by configuring non-default timers to improve performance of a specific network configuration.
Prerequisites
You must be in the router configuration context, as indicated by the
switch(config-router)# prompt.
Procedure
Reconfigure SPF throttling timers using the following command. For command details, see
timers throttle spf
timers throttle spf start-time
<milliseconds> hold-time
<milliseconds> max-wait-time
<milliseconds>
For example, use the following command to set start-time to 500ms, hold-time to 3000ms and max-wait-time to 9000ms:
switch(config-ospf-1)# timers throttle spf start-time 500 hold-time 3000 max-wait-time 9000
