The vrrp gratuitous-arp timeout command configures an interval at which the master in a VRRP group sends gratuitous ARP packets or the master in a VRRP6 group sends ND packets.
The undo vrrp gratuitous-arp timeout command restores the default interval at which the master in a VRRP group sends gratuitous ARP packets or the master in a VRRP6 group sends ND packets.
The default interval is 120 seconds.
| Parameter | Description | Value |
|---|---|---|
| timeout time | Specifies an interval at which the master in a VRRP group sends gratuitous ARP packets or the master in a VRRP6 group sends ND packets. |
The value is an integer that ranges from 30 to 1200, in seconds. |
Usage Scenario
The master in a VRRP group sends gratuitous ARP packets or the master in a VRRP6 group sends ND packets to its connected downstream switch to update the MAC entries on the downstream switch.
PrecautionsIf a short interval is used, bandwidth resources will be consumed. If a long interval is used, MAC address entries on the downstream switch cannot be updated immediately.
The interval at which the master sends gratuitous ARP or ND packets must be shorter than the aging time of MAC address entries on user devices.
Set the interval based on actual networking:
To restore the default interval at which the master sends gratuitous ARP or ND packets, run the undo vrrp gratuitous-arp timeout command in the system view.
If gratuitous ARP or ND packet do not need to be sent, run the vrrp gratuitous-arp timeout disable command in the system view.
