要在带有 L3 路由架构的网络中部署 overcloud，请完成以下步骤：
- layer-3 路由
- 配置网络基础架构的路由，以启用不同 L2 段之间的流量。您可以静态或动态配置此路由。
- DHCP-Relay
-
每个不是 undercloud 本地的 L2 片段必须提供
dhcp-relay。您必须在连接 undercloud 的 provisioning 网络段中转发 DHCP 请求到 undercloud。
注意
undercloud 使用两个 DHCP 服务器。一个用于裸机节点内省，另一个用于部署 overcloud 节点。确保您读取 DHCP 转发配置以了解在配置 dhcp-relay 时的要求。
