Hi I read ipv6forum.pdf about ipv6 It said MTU must be at least 1280 bytes (1500+) Does it mean to set the mtu over 1500 I set my linux box eth0 as 2001:db8:cafe:1111::12/64 but I can't ping it inet6 2001:db8:cafe:1111::12/64 scope global tentative ls it this problem? Thank you # ping6 2001:db8:cafe:1111::12 PING 2001:db8:cafe:1111::12(2001:db8:cafe:1111::12) 56 data bytes

No, it simply means that the minimum MTU for IPv6 is 1280.

ls it this problem? Thank you
Where are you pinging it from? also, the 2001:db8::/32 prefix is used for "documentation purposes" and might be handled differently by the TCP/IP stack.

Works fine in Linux - I've been using it (in an isolated training room setup) for years.

It is not a good idea to use the documentation prefix for anything other than documentation. How hard is it to generate a ULA and use it?
