====
The Kubernetes NMState Operator updates the network configuration of a secondary NIC. The Operator cannot update the network configuration of the primary NIC, or update the `br-ex` bridge on most on-premise networks.
On a bare-metal platform, using the Kubernetes NMState Operator to update the `br-ex` bridge network configuration is only supported if you set the `br-ex` bridge as the interface in a machine config manifest file. To update the `br-ex` bridge as a postinstallation task, you must set the `br-ex` bridge as the interface in the NMState configuration of the `NodeNetworkConfigurationPolicy` custom resource (CR) for your cluster.

{product-title} uses link:https://nmstate.github.io/[`nmstate`] to report on and configure the state of the node network. This makes it possible to modify the network policy configuration, such as by creating a Linux bridge on all nodes, by applying a single configuration manifest to the cluster.
