4.4. 配置叶网络

流程

1. 以 stack 用户身份登录 undercloud 主机。

2. 查找 stackrc undercloud 凭证文件：

   $ source ~/stackrc

3. 在新的自定义环境文件中，如 spine-leaf-ctlplane.yaml，创建一个 parameter_defaults 部分，并为使用默认 br-ex 网桥的每个叶设置 NeutronBridgeMappings 参数。

   重要

   您创建的自定义环境文件名称必须以 .yaml 或 .template 结尾。

   • 对于扁平网络映射，列出 NeutronFlatNetworks 参数中的每个 leaf，并为每个叶设置 NeutronBridgeMappings 参数：

     示例

     parameter_defaults:
       NeutronFlatNetworks: leaf0,leaf1,leaf2
       Controller0Parameters:
         NeutronBridgeMappings: "leaf0:br-ex"
     
       Controller1Parameters:
         NeutronBridgeMappings: "leaf0:br-ex"
     
       Controller2Parameters:
         NeutronBridgeMappings: "leaf0:br-ex"
     
       Compute0Parameters:
         NeutronBridgeMappings: "leaf0:br-ex"
     
       Compute1Parameters:
         NeutronBridgeMappings: "leaf1:br-ex"
     
       Compute2Parameters:
         NeutronBridgeMappings: "leaf2:br-ex"

     提示

     如需更多信息，请参阅 Chapter 17。networking (neutron)参数 ( Overcloud 参数 指南)

   • 对于 VLAN 网络映射，将 vlan 添加到 NeutronNetworkType，并使用 NeutronNetworkVLANRanges，映射叶网络的 VLAN：

     示例

     parameter_defaults:
       NeutronNetworkType: 'geneve,vlan'
       NeutronNetworkVLANRanges: 'leaf0:1:1000,leaf1:1:1000,leaf2:1:1000'
     
       Controller0Parameters:
         NeutronBridgeMappings: "leaf0:br-ex"
     
       Controller1Parameters:
         NeutronBridgeMappings: "leaf0:br-ex"
     
       Controller2Parameters:
         NeutronBridgeMappings: "leaf0:br-ex"
     
       Compute0Parameters:
         NeutronBridgeMappings: "leaf0:br-ex"
     
       Compute1Parameters:
         NeutronBridgeMappings: "leaf1:br-ex"
     
       Compute2Parameters:
         NeutronBridgeMappings: "leaf2:br-ex"

     注意

     您可以在 spine-leaf topology 中使用扁平网络和 VLAN。

4. 使用 < role>ControlPlaneSubnet 参数为每个 spine-leaf 网络添加 control plane 子网映射：

   示例

   parameter_defaults:
     NeutronFlatNetworks: leaf0,leaf1,leaf2
     Controller0Parameters:
       NeutronBridgeMappings: "leaf0:br-ex"
       ControllerControlPlaneSubnet: leaf0
     Controller1Parameters:
       NeutronBridgeMappings: "leaf0:br-ex"
       Controller1ControlPlaneSubnet: leaf0
     Controller2Parameters:
       NeutronBridgeMappings: "leaf0:br-ex"
       Controller2ControlPlaneSubnet: leaf0
     Compute0Parameters:
       NeutronBridgeMappings: "leaf0:br-ex"
       Compute0ControlPlaneSubnet: leaf0
     CephStorage0Parameters:
       CephStorage0ControlPlaneSubnet: leaf0
     Compute1Parameters:
       NeutronBridgeMappings: "leaf1:br-ex"
       Compute1ControlPlaneSubnet: leaf1
     CephStorage1Parameters:
       CephStorage1ControlPlaneSubnet: leaf1
     Compute2Parameters:
       NeutronBridgeMappings: "leaf2:br-ex"
       Compute2ControlPlaneSubnet: leaf2
     CephStorage2Parameters:
       CephStorage2ControlPlaneSubnet: leaf2

后续步骤

1. 请注意您创建的自定义网络环境文件的路径和文件名。部署 overcloud 时，稍后您将需要此信息。
2. 继续执行下一步，为虚拟 IP 地址 设置子网。
