Configuring HA to Active/Standby with L3 HA link

The following steps configure HA to Active/Standby with the L3 HA link.

  1. Configure HA to Active/Standby with the L3 HA link. To do so, browse Manage > High Availability and select Enable Stateful Synchronization.

  2. Navigate to the HA interfaces section and switch the HA Control link to L3 mode. A gateway address is unnecessary if two HA Interfaces are in the same subnet. However, if two HA interfaces are in different subnets, a proper gateway address is needed, and the default is X.X.X.1 on Azure.

  3. Add monitoring IPs for X0 and X1 is mandatory.

  4. Navigate to Device > High Availability > Status page to check whether the pair is coming together. The secondary will reboot, and seeing the device pair up may take a while.

    It is recommended that you use the latest 7.1.1-7051 or a newer firmware version to use multiple floating IP addresses in Azure.
