Router

1. Self-service network 以 virtual router 連線到對外的 provider network，provider network 欄位 router:external 必須是 external，才可以讓 selfservice network 經由 provider network 對外，這由產生 provider network 時以參數 –external 達成。
2. 以一般用戶 demo 產生 router，載入一般用戶 demo 環境變變數。

   [root@controller ~]# . demo.token
   

3. 新增 router。

   [root@controller ~]# openstack router create router
