橋在IPv6模式

Question

我創建了Ubuntu的橋樑和分配一個IPv6地址到它：

# ifconfig br1 
br1  Link encap:Ethernet HWaddr 1a:65:a0:13:71:84 
     inet6 addr: 2001:220:abcd:70::40/64 Scope:Global 
     BROADCAST MULTICAST MTU:1500 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) 

# ifconfig eth0 
eth0  Link encap:Ethernet HWaddr 78:e7:d1:c6:24:05 
     inet6 addr: 2001:220:abcd:70::25/64 Scope:Global 
     inet6 addr: fe80::7ae7:d1ff:fec6:2405/64 Scope:Link 
     UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 
     RX packets:383758 errors:0 dropped:164 overruns:0 frame:0 
     TX packets:116401 errors:0 dropped:0 overruns:0 carrier:0 
     collisions:0 txqueuelen:1000 
     RX bytes:191849350 (191.8 MB) TX bytes:8911276 (8.9 MB) 
     Interrupt:17

2001:220:abcd:70::25/128  ::       Un 0 1 2412 lo 
fe80::100c:e5ff:fe0b:8414/128 ::       Un 0 1  0 lo 
fe80::68f7:bbff:fe7f:21a5/128 ::       Un 0 1  0 lo 
fe80::7ae7:d1ff:fec6:2405/128 ::       Un 0 1 657 lo 
fe80::b40f:3aff:fe58:b0ce/128 ::       Un 0 1  0 lo 
ff00::/8      ::       U 256 0  0 br0 
ff00::/8      ::       U 256 0  0 tap0 
ff00::/8      ::       U 256 0  0 tap1 
ff00::/8      ::       U 256 0  0 br1 
ff00::/8      ::       U 256 0  0 eth0 
::/0       ::       !n -1 1 3383 lo 

我無法在主機上平BR1。但是，我可以ping另一個IP地址爲2001：220：abcd：70 :: 26的Ubuntu系統。 另外，br1不會顯示在'ifconfig'的輸出中;我必須做'ifconfig br1'來列出它。

對此行爲有何想法？

謝謝！

我想你必須在eth0接口上禁用2001 IP，因爲轉發接口不應該有IP。
