Hi
Thank you for your help
I type the ifconfig -a
there is ipv6 address
inet6 fe80::20c:29ff:fe3c:92a1/64 scope link tentative
i also add one
inet6 2001:db8:cafe:1111::12/64 scope global tentative
but both are not pingable by ping6
Here are commands you suggested me to run
route -n -A inet6
Kernel IPv6 routing table

I can't ping ipv6.google.com but I should ping the eth0 ipv6 as it is host ip
address. Right?
Thank you for your help.

Hi
I used the command "ip -6 addr add
2001:DB8:CAFE:1111::12/64 dev eth0"
to add ipv6 address and can see it in ifconfig
but can't ping it
Why?
Thank you
# ping6 2001:db8:cafe:1111::12
PING 2001:db8:cafe:1111::12(2001:db8:cafe:1111::12) 56

hi,
have you correctly set gateway? Send `ip -6 route` and
`route -n -A
inet6` to us. What about to ping ipv6.google.com from this
pc?
Where did you run ping command? Have you IPv6 enabled
there? "From ::1"
looks like something is misconfigured..

can you ping6 ::1 ?
what does ip6tables -L -n
show?
Have you looked at
