The Hybrid Overlay feature allows to connect to external Windows networks. For that, a config needs to be added to networks.operator.openshift.io similar to this: spec: defaultNetwork: type: OVNKubernetes ovnKubernetesConfig: hybridOverlayConfig: hybridClusterNetwork: - cidr: 10.132.0.0/14 hostPrefix: 23 However OVN Kubernetes already has that CIDR has default value, thus there's no point to forcing user to specify that. Moreover, on the hybrid overlay external GW work that is been developed we want to leverage the VXLAN tunnels created by hybrid overlay but we don't care about Windows networks.
Looks good to me on 4.5.0-0.nightly-2020-04-13-133703 # oc patch network.operator cluster --type=merge -p '{"spec":{"defaultNetwork":{"ovnKubernetesConfig":{"hybridOverlayConfig":{}}}}}' Network operator reconcile this change successfully and restarts pods under openshift-ovn-kubernetes project to reflect the same
