LABEL DESCRIPTION
Enable VRRP
Group
Select this to make the specified interface part of the virtual router. Clear this to
take the specified interface out of the virtual router. Enabling a VRRP group has the
ZyWALL monitor the connection of the group’s interface.
Name This field is read-only if you are editing the VRRP group. Type the name of the
VRRP group. This field must be unique in the ZyWALL, but it is not used in the
virtual router. The virtual router uses the VRID. The name can consist of
alphanumeric characters, the underscore, and the dash and may be up to fifteen
characters long.
Description Type the description of the VRRP group. This field is only for your reference. It may
be up to sixty printable ASCII characters long.
Interface Name Select the interface in this device that is part of the virtual router. You can only
select interfaces that have static IP addresses. Connect the interface to the same
subnet as the group’s interface on the other ZyWALL.
Manage IP 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
so the backup ZyWALL cannot synchronize with the master via this VRRP
interface.
Subnet Mask Enter the subnet mask of the interface’s management IP address.
Role Select the role that you want the interface to play in the virtual router. Choices are:
Master - This interface is the master interface in the virtual router. The interface
always uses its virtual IP address when its status is active.
Note: Do not set this field to Master for two or more ZyWALLs in the
same virtual router (same VR ID).
Backup - This interface is a backup interface in the virtual router. The current role
depends on the other ZyWALLs in the virtual router.
Priority This field is available if the selected interface is a Backup interface. Type the
priority of the backup interface. The backup interface with the highest value takes
over the role of the master interface if the master interface becomes unavailable.
The priority must be between 1 and 254. (The master interface has priority 255.)
