<pre wrap="">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
Destination Next Hop Flags Metric Ref Use Iface
2001:db8:cafe:1111::/64 :: U 256 0 0 eth0
fe80::/64 :: U 256 0 0 eth0
::1/128 :: U 0 2 1 lo
ff00::/8 :: U 256 0 0 eth0
ip -6 route
2001:db8:cafe:1111::/64 dev eth0 metric 256 expires 21334307sec mtu 1500 advmss 1440 hoplimit 4294967295
fe80::/64 dev eth0 metric 256 expires 21330690sec mtu 1500 advmss 1440 hoplimit 4294967295
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,
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..
