红帽全球峰会6.4.2. 网络要求
所选网络拓扑必须在节点间产生直接 IP 连接。跨基础架构的最小有效 MTU 应当是用于部署的最大 MTU。可以接受使用更低的 MTU。
如需更多信息，请参阅使用 OpenShift Container Platform 4.x 了解和验证 MTU 设置。延迟需求最终由使用网络的服务定义。有关要求的详情，请参阅与 etcd 和存储相关的部分。
除了基本网络要求外，您还需要考虑应用的访问方式。OpenShift Container Platform 还需要顶级全局服务负载平衡(GSLB)方法，以便外部流量连接到 OpenShift Container Platform control plane 服务和入口控制器。
