TEST PROCEDURE

       NUT      TN
        |       | 
        |       | initialize NUT (as a DHCPv6 Server)
        |       | 
        | <---- | Solicit (w/ Rapid Commit option,IA_NA, IA Address)
        | ----> | Reply   (w/ Rapid Commit option,IA_NA, IA Address) (*1)
        |       | after 10s
        | <---- | Solicit (w/ Rapid Commit option,IA_NA, IA Address)
        | ----> | Reply   (w/ Rapid Commit option,IA_NA, IA Address) (*2)
        |       | 

JUDGEMENT

 PASS: The Reply message must include IA_NA option & IA address option.
           And the option's format must be based on the RFC's description.
           (see the above Verification Points )
           The preferred lifetimes and life times in Reply messages are same.
           NUT Ignores the values in the Solicit messages.(Not change the value)
