查询 tenant

[root@station140 ~(network_admin)]#  keystone tenant-list+----------------------------------+----------+---------+|                id                |   name   | enabled |+----------------------------------+----------+---------+| 9467f30b8bba4770a06a687e4584636b |  cloud   |   True  |+----------------------------------+----------+---------+

创建路由连接到外部网络, 这个路由可以与内部网络进行连接
你可以创建过程中指定一个 tenant, 利用参数 --tenant-id 9467f30b8bba4770a06a687e4584636b 进行定义
