The fib regularly-refresh disable command disables the FIB entry update function.
The undo fib regularly-refresh disable command enables the FIB entry update function.
By default, the FIB entry update function is enabled.
Usage Scenario
By default, a device starts FIB entry update 30 minutes after a device is powered on, and the update is performed regularly at an interval of 1 minute. Updating FIB entries occupy system resources. To avoid a high CPU usage within a short period, run the fib regularly-refresh { interval interval [ entry-number entry-number ] | entry-number entry-number | cycle-interval cycle-interval } command to set the entire FIB entry update interval or the FIB entry update interval per cycle to a larger value or reduce the number of FIB entries updated per cycle. If the CPU usage problem still persists, run the fib regularly-refresh disable command to disable the FIB entry update function.
Precautions
Disabling the FIB entry update function may cause a failure to rectify certain hardware faults in time. Exercise caution when running the fib regularly-refresh disable command.
