流程

1. 以 stack 用户身份登录 undercloud 主机。

2. $ source ~/stackrc

3. 示例

   $ vi /home/stack/templates/my-environment.yaml

4. parameter_defaults:
     NeutronMechanismDrivers: ['openvswitch', 'l2population']
     NeutronEnableL2Pop: 'True'
     NeutronEnableARPResponder: true

5. 重要

   但是，环境文件的顺序非常重要，因为后续环境文件中定义的参数和资源更为优先。

   示例

   $ openstack overcloud deploy --templates \
   -e <your_environment_files> \
   -e /home/stack/templates/my-environment.yaml

验证

1. $ openstack network agent list -c ID -c Binary
