我尝试使用ip tunnel add命令创建IPIP tunel。现在我想删除它,但它不会消失!

tunl0     Link encap:IPIP Tunnel  HWaddr   
          NOARP  MTU:1480  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

$ sudo ifdown tunl0
ifdown: interface tunl0 not configured
$ sudo ifconfig tunl0 down
$ /sbin/ip tunnel del tunl0
delete tunnel tunl0 failed: Operation not permitted

我该怎么办?
