在 ubuntu 焦点上使用 linux 桥接和 ipv6 时，我遇到了一个我想了解的问题。
当我手动设置网桥mac地址时，网桥ipv6地址不再起作用，为什么？
使用系统分配的 MAC 地址进行桥接 [工作正常]
root@node:~# ip link del dev brv6
root@node:~# ip link add name brv6 type bridge
root@node:~# ip -6 address add dev brv6 scope global fdfe::401/118
root@node:~# ip link set dev brv6 up
root@node:~# ping -c2 fdfe::401

谢谢你的帮助。
