Review the documentation of the CNI plugin (OpenShift SDN or OVN-Kubernetes) in use by the cluster, and confirm that it supports ingress and egress network policies. OpenShift Container Platform uses a software-defined networking (SDN) approach to offer a unified cluster network that enables communication between Pods across the OpenShift Container Platform cluster. This Pod network can be established and maintained by either the OpenShift SDN plugin, which configures an overlay network using Open vSwitch (OVS), or by the OVN-Kubernetes plugin.
