Well, everything looks OK in your configuration. I'm sorry to say that I
don't have a good idea why "ping 131.107.65.121" works well but "ping6
::131.107.65.121" is unreliable. My only guess is that something in your
network (maybe the firewall?) is handling encapsulated IPv6 packets in a
slow path and so they get a higher drop rate.

Let me clarify this. If you run
ping 131.107.65.121
then it works great.
But if you try
ping6 ::131.107.65.121
then you get some replies but most pings time out?
Can you send us
a) Information about your hardware configuration.
b) Information about your network topology? How are you connected to the
internet?
c) The output of "ipv6 if" and "ipv6 rt".
Thanks,
Rich

I AM A CHINESE STUDENT,NOW,I HAVE INSTALLED WINDOWS2000 AND BUILD A
IPV6 STACK .USING " IPV6 "COMMAND,I TRY TO CONNECT WITH
6TO4(::131.107.65.121).WHEN I HAVE FINISHED ALL THE COMMAND ,I TYPE
" PING6 ::131.107.65.121"
THE RESULT IS,TOO MUCH "REQUEST TIMMED OUT" AND SHOW REPLY ONCE IN A
WHILE,HOWEVER,IF I TYPE "PING 131.107.65.121" ,THE RESULT IS NORMAL.WHY?
