1. 載入管理者環境變變數。

   [root@controller ~]# . admin.token
   

2. 列出 agent，確認可以使用 neutron agent，如果只有 provider network，會有以下三種 agent。

   [root@controller ~]# openstack network agent list
   +--------------------------------------+--------------------+------------+
   | ID                                   | Agent Type         | Host       |
   +--------------------------------------+--------------------+------------+
   | 3eb768a6-2f98-4c71-9c92-a964677c58d8 | DHCP agent         | controller |
   | 532abb67-c6eb-4768-92e3-722684315909 | Linux bridge agent | controller |
   | c4d53419-f893-4139-a4eb-3dfe45a4f063 | Metadata agent     | controller |
   +--------------------------------------+--------------------+------------+
   -------------------+-------+-------+---------------------------+
    Availability Zone | Alive | State | Binary                    |
   -------------------+-------+-------+---------------------------+
    nova              | :-)   | UP    | neutron-dhcp-agent        |
    None              | :-)   | UP    | neutron-linuxbridge-agent |
    None              | :-)   | UP    | neutron-metadata-agent    |
   -------------------+-------+-------+---------------------------+
   

3. 列出 agent，確認可以使用 neutron agent，如果也有 self-service network，則會多一項 L3 agent。

   [root@controller ~]# . admin.token 
   [root@controller ~]# openstack network agent list
   +--------------------------------------+--------------------+------------+-
   | ID                                   | Agent Type         | Host       | 
   +--------------------------------------+--------------------+------------+-
   | 08c0fc32-63ff-44cd-8464-f756dfac0c8e | DHCP agent         | controller | 
   | 87c9eccb-24f6-4046-bcf2-324532c88767 | Linux bridge agent | controller | 
   | b5276b97-37a4-4a0e-828d-c0f5a6b1c947 | Metadata agent     | controller | 
   | f0c9588f-161e-4b8a-9ed5-bdfe3203e4eb | L3 agent           | controller | 
   +--------------------------------------+--------------------+------------+-

   Availability Zone | Alive | State | Binary                    |
   ------------------+-------+-------+---------------------------+
   nova              | :-)   | UP    | neutron-dhcp-agent        |
   None              | :-)   | UP    | neutron-linuxbridge-agent |
   None              | :-)   | UP    | neutron-metadata-agent    |
