Active-Passive Mode Device HA with Bridge Interfaces
Here are two ways to avoid a broadcast storm when you connect the bridge interfaces on two
ZyWALL/USGs.
First Option for Connecting the Bridge Interfaces on Two ZyWALL/USGs
The first way is to activate Device HA before connecting the bridge interfaces as shown in the
following example.
Make sure the bridge interfaces of the master ZyWALL/USG (A) and the backup ZyWALL/USG (B)
1
are not connected.
Configure the bridge interface on the master ZyWALL/USG, set the bridge interface as a monitored
2
interface, and activate Device HA.

DESCRIPTION
Enter the interface's IP address for management access. You can use this IP address to
access the ZyWALL/USG whether it is the master or a backup. This management IP
address should be in the same subnet as the interface IP address.
Enter the subnet mask of the interface's management IP address.
Click OK to save your changes back to the ZyWALL/USG.
Click Cancel to exit this screen without saving your changes.
