路由创建属于网络部分，所以只能是neutron模块可以完成，路由的具体创建步骤如下：
1. 创建路由命令：
(neutron-server)[neutron@B-OPS-9-3 /]$ neutron router-create onlyone
可以看见，onlyone的路由创建成功,其id=481b4902-2b3-4fec-a757-d90688b73558 。可查看其信息：
下面继续配置子网，使子网连接到路由
2. 查看当前子网：
(neutron-server)[neutron@B-OPS-9-3 /]$ neutron net-list
这里以 fly-net为例。
3. 添加子网（subnet）到路由，注意这里是子网，是subnets这一列（最后一列）：
(neutron-server)[neutron@B-OPS-9-3 /]$ neutron router-interface-add \
481b4902-2b3-4fec-a757-d90688b73558 \ #路由id
92e158f7-0771-4fa3-ad36-e67e5608d151 # 子网subnet id
说明添加子网成功！
