updates its ARP table. This way the ZyXEL Device has a correct gateway ARP entry to

forward packets through the backup gateway. If ackGratuitous is off or not set to force

updates, the ZyXEL Device will not update the gateway ARP entry and cannot forward

packets through gateway B.

Figure 300 Backup Gateway

Updating the ARP entries could increase the danger of spoofing attacks. It is only

recommended that you turn on ackGratuitous and force update if you need it like in the

previous backup gateway example. Turning on the force updates option is more dangerous

than leaving it off because the ZyXEL Device updates the ARP table even when there is an

existing entry.
