This section describes how to configure the example virtual clustering configuration shown in Figure 198. This configuration includes two virtual domains, root and Eng_vdm and includes VDOM partitioning that sends all root VDOM traffic to 620_ha_1 and all Eng_vdom VDOM traffic to 620_ha_2. The traffic from the internal network and the engineering network is distributed between the two FortiGate units in the virtual cluster. If one of the cluster units fails, the remaining unit will process traffic for both VDOMs.

The procedures in this example describe some of many possible sequences of steps for configuring virtual clustering. For simplicity many of these procedures assume that you are starting with new FortiGate units set to the factory default configuration. However, this is not a requirement for a successful HA deployment. FortiGate HA is flexible enough to support a successful configuration from many different starting points.
