INITIALIZATION


PRE-TEST SEQUENCE

        After all zone information are transferred between primary DNS server7 (TN) 
        and slave DNS server1 (NUT), following pre-test sequence is performed.

TEST PROCEDURE

        This test sequence is following.
        NOTE: SOA's parameter and $TTL are same as above sec.example.com zone information.
              TN includes NS7 and NS1.sub.example.com into Authority section as type = NS.
              Also TN includes NS7 and NS1.sub.example.com address into Additional section.
              Thus NUT may reply to answer client with Authority and Additional section including
              those values.

        This test sequence is following.
        1. DNS Server7 (TN) sends NOTIFY request to DNS Server1 (NUT).
        2. DNS Server1 (NUT) sends NOTIFY response to DNS Server7 (TN). (Judgment *2)


JUDGMENT

        2. DNS Server1 (NUT) sends NOTIFY response to DNS Server7 (TN).
