> The configuration of the loopback interfaces is performed within the guest OS. This configuration is not performed or managed by Azure. Without this configuration, the rules will not function. Health probe definitions use the DIP of the VM rather than the loopback interface representing the DSR Frontend. Therefore, your service must provide probe responses on a DIP port that reflect the status of the service offered on the loopback interface representing the DSR Frontend.

The Floating IP rule type is the foundation of several load balancer configuration patterns. One example that is currently available is the [Configure one or more Always On availability group listeners](/azure/azure-sql/virtual-machines/windows/availability-group-listener-powershell-configure) configuration. Over time, we will document more of these scenarios.
