26.5 Device HA Technical Reference

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
ZyWALLs.
First Option for Connecting the Bridge Interfaces on Two ZyWALLs
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 (A) and the backup ZyWALL (B) are not
1
connected.

DESCRIPTION
Select this to have device HA monitor the status of this interface's connection.
This identifies the interface.
Note: Do not connect the bridge interfaces on two ZyWALLs without device HA activated on
both. Doing so could cause a broadcast storm.
Either activate device HA before connecting the bridge interfaces or disable the bridge
interfaces, connect the bridge interfaces, activate device HA, and finally reactivate the
bridge interfaces.
This is the interface's (static) IP address and subnet mask in the virtual router. Whichever
ZyWALL is currently serving as the master uses this virtual router IP address and subnet
mask. These fields are blank if the interface is a DHCP client or has no IP settings.
Enter the interface's IP address for management access. You can use this IP address to
access the ZyWALL 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.
