See documentation for the latest supported version 3 or the latest supported version 4.3.3.2. 网络注意事项
在从 OpenShift Container Platform 3.11 转换到 OpenShift Container Platform 4.7 时，请考虑以下与网络相关的变化。
网络隔离模式
虽然用户经常切换为使用 ovn-multitenant，但是 OpenShift Container Platform 3.11 的默认网络隔离模式是 ovs-subnet。OpenShift Container Platform 4.7 的默认网络隔离模式由网络策略控制。
如果您的 OpenShift Container Platform 3.11 集群使用了 ovs-subnet 或 ovs-multitenant 模式，则建议在 OpenShift Container Platform 4.7 集群中使用网络策略。网络策略由上游社区支持，它更灵活并提供 ovs-multitenant 的功能。如果您要在 OpenShift Container Platform 4.7 中使用网络策略时仍然希望维持 ovs-multitenant 的行为，请按照以下步骤使用网络策略配置多租户隔离。
如需更多信息，请参阅关于网络策略。
