6.3 Device HA

This example is going to show you how to set up device HA as illustrated below.

Figure 66 Device HA Example

In this example, router A is the default gateway for the network and uses IP address
192.168.1.1. This is the default gateway IP address for the network. There are two ZyWALL
routers to ensure this gateway is available. Router A is the master; router B is the backup.
Router B has a management IP address of 192.168.1.101.
The ZyWALL has its default settings. Configure the master first because you can synchronize
the backup with the master later.

6.3.1 Set up DNS for the Virtual Router

You can use a fully-qualified domain name, instead of an IP address, for the virtual router. If
you want to do this, you should set up DNS before you configure the VRRP groups and
synchronization. In this example, you are going to use the IP address.

6.3.2 Set up the VRRP Groups on the Master

You have to set up one VRRP group for each interface with a static IP address on which you
want to set up device HA. In this example, create two VRRP groups, one for ge1 and one for
ge4.
1 Click Device HA > VRRP Group, and then click the Add icon.
2 Give the VRRP group a name and virtual router ID, and select the interface ge1. This is
the master router, and you are not going to use authentication. Click OK.
