清除OpenStack网络与路由

下面，我们以删除一个路由设备为例，讲解整个过程（以下命令都在控制节点执行）

列出所有路由设备，获得要删除的路由器id

# neutron router-list

[root@controller ~]# neutron router-list
+--------------------------------------+-------+-----------------------------------------------------------------------------+
| id                                   | name  | external_gateway_info                                                       |
+--------------------------------------+-------+-----------------------------------------------------------------------------+
| 9e397a85-2284-4809-8143-bee6bd075cf5 | route | {"network_id": "f9684976-0d44-4bd8-9116-048602a6c3e1", "enable_snat": true} |
+--------------------------------------+-------+-----------------------------------------------------------------------------+

 根据路由器id，删除其网关端口

# neutron router-gateway-clear <router_id>

[root@controller ~]# neutron router-gateway-clear 9e397a85-2284-4809-8143-bee6bd075cf5
Removed gateway from router 9e397a85-2284-4809-8143-bee6bd075cf5

 根据路由设备id，列出其其他端口

# neutron router-port-list <router_id>

[root@controller ~]# neutron router-port-list 9e397a85-2284-4809-8143-bee6bd075cf5
+--------------------------------------+------+-------------------+------------------------------------------------------------------------------------+
| id                                   | name | mac_address       | fixed_ips                                                                          |
+--------------------------------------+------+-------------------+------------------------------------------------------------------------------------+
| 5163bb3d-03d6-471d-b8fc-81d0405110e2 |      | fa:16:3e:b6:ca:00 | {"subnet_id": "d8a13476-2952-4618-a968-6a7d524b76c2", "ip_address": "192.168.0.1"} |
+--------------------------------------+------+-------------------+------------------------------------------------------------------------------------+

 根据路由器id与subnet_id删除路由器其他端口

 # neutron router-interface-delete <router-id> <subnet-id>

[root@controller ~]# neutron router-interface-delete 9e397a85-2284-4809-8143-bee6bd075cf5 d8a13476-2952-4618-a968-6a7d524b76c2
Removed interface from router 9e397a85-2284-4809-8143-bee6bd075cf5.

 最后删除路由

# neutron router-delete <router-id>

[root@controller ~]# neutron router-delete 9e397a85-2284-4809-8143-bee6bd075cf5
Deleted router: 9e397a85-2284-4809-8143-bee6bd075cf5

列出所有使用网络的端口

# neutron port-list

[root@controller ~]# neutron port-list

+--------------------------------------+------------+------------------+-------------------------------------------------------+

 列出网络，获得要删除的网络id
