You can use this feature when the `ProvisioningNetwork` configuration setting is set to `Managed`. To use this feature, you must set the `virtualMediaViaExternalNetwork` configuration setting to `true` in the `provisioning` custom resource (CR). You must also edit the machineset to use the API VIP address.

After installing and configuring the MetalLB Operator, you can deploy MetalLB to provide a native load balancer implementation for services on bare-metal clusters. Other on-premise infrastructures that are like bare metal can also benefit. + +The Operator introduces a custom resource, `AddressPool`. You configure address pools with ranges of IP addresses that MetalLB can assign to services. When you add a service of type `LoadBalancer`, MetalLB assigns an IP address from a pool. + +For this release, Red Hat only supports using MetalLB in layer 2 mode. + +For more information, see xref:../networking/metallb/about-metallb.adoc#about-metallb[About MetalLB and the MetalLB Operator]. + [id="ocp-4-9-storage"] === Storage
