The ipv6 fib regularly-refresh interval command configures a refresh interval each time for the IPv6 FIB.
The undo ipv6 fib regularly-refresh interval command restores the default refresh interval each time for the IPv6 FIB.
By default, the refresh interval each time is 1s.
ipv6 fib regularly-refresh interval interval
undo ipv6 fib regularly-refresh interval [ interval ]
| Parameter | Description | Value |
|---|---|---|
| interval | Specifies an interval at which FIB entries are refreshed. | The value is an integer ranging from 1 to 300, in seconds. |
Usage Scenario
IPv6 FIB 24-hour refresh occupies system resources, including CPU and memory resources. The longer a refresh interval is configured, the minor negative impacts it has on other services. You can configure flexibly a refresh interval 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 configured refresh interval is too long, the lower layer hardware entries cannot be refreshed periodically, and this affects IPv6 route forwarding.
