红帽全球峰会10.5. 网络接口布局示例
以下 Controller 节点 NIC 模板片段演示了如何配置自定义网络场景，使控制组与 OVS 网桥分开：

此模板使用三个网络接口，并将多个标记的 VLAN 设备分配给编号的接口 nic1 到 nic3。在 nic2 和 nic3 上，此模板创建托管存储、租户和外部网络的 OVS 网桥。因此，它会创建以下布局：
NIC1 (Provisioning)
- Provisioning/Control Plane
NIC2 和 NIC3 （管理）
- 内部 API
- 存储
- 存储管理
- 租户网络(VXLAN 隧道)
- 租户 VLAN/提供程序 VLAN
- 外部（公共 API）
- 外部 VLAN （利用 IP/SNAT）
