路由建立屬於網路部分，所以只能是neutron模組可以完成，路由的具體建立步驟如下：

1.  建立路由命令：

(neutron-server)[[email protected] /]$ neutron router-create onlyone

可以看見，onlyone的路由建立成功,其id=481b4902-2b3-4fec-a757-d90688b73558 。可檢視其資訊：

下面繼續配置子網，使子網連線到路由

2. 檢視當前子網：

(neutron-server)[[email protected] /]$ neutron net-list

這裡以  fly-net為例。

3.  新增子網（subnet）到路由，注意這裡是子網，是subnets這一列（最後一列）：

(neutron-server)[[email protected] /]$ neutron router-interface-add \ 

481b4902-2b3-4fec-a757-d90688b73558 \  #路由id

92e158f7-0771-4fa3-ad36-e67e5608d151   # 子網subnet id

說明新增子網成功！
