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：

              - type: vlan

                # NIC 4 - Management
                - type: interface

                  - ip_netmask: {get_param: ManagementIpSubnet}

                  - default: true
                    next_hop: {get_param: ManagementInterfaceDefaultRoute}

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：
