My link layer address is 02:03:7F:BE:F0:A0.
So my DUID becomes..
option dhcp6.server-id "\000\003\000\001\002\003\177\276\360\240";
Is it correct?
Thanks,
Madhu

It's pretty clear from the RFC:
http://tools.ietf.org/html/rfc3315#section-9.4
So for ethernet that would be
option dhcp6.server-id "\000\003\000\001<your ethernet mac address in octal here>"
