IPv6 minimum Link MTU

Hi All,

  When I was going through the Doc CD for IPv6,I read about the "Minimum
Link MTU is 1280 octets in IPv6".Even when referred the RFC 2460 (IPv6
specification),it highlights the same.I am just curious about the
significance of that number "1280 octets".How that is derived ?.Even I
didn't know,what is the significance of the number 68 octets,which is
minimum MTU size for Ipv4 .

Any clarification is really appreciated.

Thanks for the help
