Description
For ASR replicated items Azure supports to set a target load balancer backend pool:
- Portal: https://learn.microsoft.com/en-us/azure/site-recovery/azure-to-azure-customize-networking#customize-failover-and-test-failover-networking-configurations
- REST: https://learn.microsoft.com/en-us/rest/api/site-recovery/replication-protected-items/create?tabs=HTTP#enableprotectioninputproperties:~:text=recoveryLBBackendAddressPoolIds
In the azurerm provider it is not supported yet. Please integrate that feature so we can failover our VM smoothly to the defined LB backend pool. We are using Zone2Zone replication, so for us the backend pool ID stays the same.
The network_interface block can be extended by the recovery_lb_backend_pool_id.
