Re: [CentOS] what wrong about my ipv6 address
Dne 7.3.2011 20:56, ann kok napsal(a): Hi I used the command ip -6 addr add 2001:DB8:CAFE:::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:::12 PING 2001:db8:cafe:::12(2001:db8:cafe:::12) 56 data bytes From ::1 icmp_seq=1 Destination unreachable: Address unreachable From ::1 icmp_seq=2 Destination unreachable: Address unreachable From ::1 icmp_seq=3 Destination unreachable: Address unreachable From ::1 icmp_seq=5 Destination unreachable: Address unreachable From ::1 icmp_seq=6 Destination unreachable: Address unreachable From ::1 icmp_seq=7 Destination unreachable: Address unreachable From ::1 icmp_seq=9 Destination unreachable: Address unreachable From ::1 icmp_seq=10 Destination unreachable: Address unreachable From ::1 icmp_seq=11 Destination unreachable: Address unreachable 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?

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:::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 RefUse Iface 2001:db8:cafe:::/64 :: U 25600 eth0 fe80::/64 :: U 25600 eth0 ::1/128 :: U 0 21 lo ff00::/8:: U 25600 eth0 ip -6 route 2001:db8:cafe:::/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.
