Openstack的刪除錯誤網橋，虛擬網路

除錯

在實驗openstack的各種網路模式時，可能會產生一些錯誤的網路指向，需要刪除那些網橋。

執行前

[root@node-9 ~]# ifconfig
br40      Link encap:Ethernet  HWaddr FA:16:3E:F3:68:A4  
          inet addr:172.17.39.4  Bcast:172.17.39.255  Mask:255.255.255.0
          inet6 addr: fe80::dcfb:8bff:fe62:5171/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:5 errors:0 dropped:0 overruns:0 frame:0
          TX packets:34 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:872 (872.0 b)  TX bytes:4529 (4.4 KiB)
vlan40    Link encap:Ethernet  HWaddr FA:16:3E:F3:68:A4  
          inet6 addr: fe80::f816:3eff:fef3:68a4/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:40 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 b)  TX bytes:4977 (4.8 KiB)

執行命令

[root@node-9 ~]# vconfig rem vlan40
Removed VLAN -:vlan40:-
[root@node-9 ~]# ifconfig br40 down
[root@node-9 ~]# brctl delbr br40

在次執行ifconfig,將看到不在存在這2個虛擬網路和網橋了
