Chapter 9 High Availability for FortiOS 5.0 : Full mesh HA : Example: full mesh HA configuration : FortiGate-620B full mesh HA configuration
  
FortiGate-620B full mesh HA configuration
The two FortiGate-620B units (620_ha_1 and 620_ha_2) can be operating in NAT/Route or Transparent mode. Aside from the standard HA settings, the FortiGate-620B configuration includes the following:
The port5 and port6 interfaces configured as heartbeat interfaces. A full mesh HA configuration also includes redundant HA heartbeat interfaces.
The port1 and port2 interfaces added to a redundant interface. Port1 is the active physical interface in this redundant interface. To make the port1 interface the active physical interface it should appear above the port2 interface in the redundant interface configuration.
The port3 and port4 interfaces added to a redundant interface. Port3 is the active physical interface in this redundant interface. To make the port3 interface the active physical interface it should appear above the port4 interface in the redundant interface configuration.
