The ipv6 fib regularly-refresh entry-number command configures the number of entries refreshed each time for the IPv6 FIB.
The undo ipv6 fib regularly-refresh entry-number command restores the default number of entries refreshed each time for the IPv6 FIB.
By default, the number of entries refreshed each time for the IPv6 FIB is 100.
ipv6 fib regularly-refresh entry-number entry-number
undo ipv6 fib regularly-refresh entry-number [ entry-number ]
| Parameter | Description | Value |
|---|---|---|
| entry-number | Specifies the number of FIB entries refreshed each time. | The value is an integer ranging from 20 to 2000. |
Usage Scenario
IPv6 FIB 24-hour refresh occupies system resources, including CPU and memory resources. The less the number of entries refreshed is configured, the minor negative impacts it has on other services. Users can configure flexibly the number of entries refreshed based on system resources.
To reduce the system resource usage, run the ipv6 fib regularly-refresh entry-number command and the ipv6 fib regularly-refresh interval command to adjust the interval at which FIB entries are refreshed and the number of FIB entries refreshed each time.
Prerequisites
IPv6 FIB 24-hour refresh has been enabled. By default, this function has been enabled. If not, run the undo ipv6 fib regularly-refresh disable command in the system view to enable it.
Configuration Impact
If the number of entries refreshed is too small, the lower layer hardware entries cannot be refreshed periodically, and this affects IPv6 route forwarding.
