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.
