红帽全球峰会11.5. 网络接口布局示例
以下示例 Controller 节点 NIC 模板片断如何配置自定义网络场景，使其保持控制组与 OVS 网桥独立：

此模板使用四个网络接口，并将多个标记的 VLAN 设备分配给编号的接口 nic1 到 nic4。在 nic3 上，它创建托管 Storage 和租户网络的 OVS 网桥。因此，它会创建以下布局：
NIC1 (Provisioning)：
- 置备/Control Plane
NIC2 (Control Group)
- 内部 API
- 存储管理
- 外部（公共 API）
NIC3 (Data Group)
- 租户网络(VXLAN 隧道)
- 租户 VLAN/提供程序 VLAN
- 存储
- 外部 VLAN （浮动 IP/SNAT）
NIC4 （管理）
- 管理
