Sorry, I didn't check the forum several days and didn't reply in time.
My ISP is CERNET, Chinese education and research network. ipv6 addresses are distributed via DHCP.
Code:
~$ ip -6 route
2402:f000:5:7201::/64 dev eth0 proto kernel metric 256 expires 2592043sec
fe80::/64 dev eth0 proto kernel metric 256
default via fe80::205:85ff:fe7a:4cb2 dev eth0 proto kernel metric 1024 expires 1681sec
~$ ip -6 neigh
fe80::205:85ff:fe7a:4cb2 dev eth0 router FAILED
~$ sudo rdisc6 eth0
Soliciting ff02::2 (ff02::2) on eth0...

It seems that the ipv6 router does not work, and i have tried to connect to the same wired network in winxp or win7, it works, without any problem.
In addition, i try to use a wireless route to change the wired to wireless, and connect to the wireless network in debian gnu/linux, it works. then i run the same command as follows:
Code:
~$ ip -6 route
it shows the same as previous one, with the 'eth0' replaced by 'wlan0'
~$ ip -6 neigh
