我在Ubuntu上创建了一个桥接器并为其分配了一个IPv6地址:

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

# ifconfig eth0

      inet6 addr: fe80::7ae7:d1ff:fec6:2405/64 Scope:Link

      RX bytes:191849350 (191.8 MB)  TX bytes:8911276 (8.9 MB)
      Interrupt:17

我无法在主机上ping br1。但是,我能够ping另一个IP为2001:220:abcd:70 :: 26的Ubuntu系统。 另外,br1没有显示在'ifconfig'的输出中;我必须做'ifconfig br1'来列出它。

对此行为的任何想法?

谢谢!

我猜你必须在eth0接口上禁用2001 IP,因为转发接口不应该有IP。
