Description Ricardo Carrillo Cruz 2020-04-13 15:13:17 UTC 
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.
