 The OVN-Kubernetes CNI plugin supports `layer2`, `layer3`, and `localnet` topologies for secondary pod networks. However, for the primary network, or the main network that all pods are attached to, only a `layer3` topology is supported. This allows for network models where all pods in the cluster were part of the same global `layer3` network, but restricts the ability to customize primary network configurations.
