Click this button to display a greater or lesser number of configuration fields.
Device Role
Select the Device HA role that the Zyxel Device plays in the virtual router. Choices are:
Master
- This Zyxel Device is the master Zyxel Device in the virtual router. This Zyxel Device uses
the virtual IP address for each monitored interface.
Note: Do not set this field to
Master
for two or more Zyxel Devices in the same
virtual router (same cluster ID).
Backup
- This Zyxel Device is a backup Zyxel Device in the virtual router. This Zyxel Device
does not use any of the virtual IP addresses.
Priority
This field is available for a backup Zyxel Device. Type the priority of the backup Zyxel Device.
The backup Zyxel Device with the highest value takes over the role of the master Zyxel
Device if the master Zyxel Device becomes unavailable. The priority must be between 1 and
254. (The master interface has priority 255.)
Enable
Preemption
This field is available for a backup Zyxel Device. Select this if this Zyxel Device should become
the master Zyxel Device if a lower-priority Zyxel Device is the master when this one is enabled.
(If the role is master, the Zyxel Device preempts by default.)
Cluster Settings
Cluster ID
Type the cluster ID number. A virtual router consists of a master Zyxel Device and all of its
backup Zyxel Devices. If you have multiple Zyxel Device virtual routers on your network, use a
different cluster ID for each virtual router.
Authentication
Select the authentication method the virtual router uses. Every interface in a virtual router
must use the same authentication method and password. Choices are:
None
- this virtual router does not use any authentication method.
Text
- this virtual router uses a plain text password for authentication. Type the password in the
field next to the radio button. The password can consist of alphanumeric characters, the
underscore, and some punctuation marks (+-/*= :; .! @$&%#~ ‘ \ () ), and it can be up to
eight characters long.
IP AH (MD5)
- this virtual router uses an encrypted MD5 password for authentication. Type the
password in the field next to the radio button. The password can consist of alphanumeric
characters, the underscore, and some punctuation marks (+-/*= :; .! @$&%#~ ‘ \ () ), and it
can be up to eight characters long.

Interface
This field identifies the interface. At the time of writing, Ethernet and bridge interfaces can be
included in the Device HA virtual router. The member interfaces of any bridge interfaces do
not display separately.
Virtual Router IP
/ Netmask
This is the master Zyxel Device’s (static) IP address and subnet mask for this interface. If a
backup takes over for the master, it uses this IP address. These fields are blank if the interface
is a DHCP client or has no IP settings.
