TEST PROCEDURE

 The following tests are prepared in this test package. See INDEX file.

Test for a Host and Router

   DAD Fail when NUT received Valid NS in random delaying phase on Stateless Link-local address autoconfiguration

Test sequence

  TN(or X)                   NUT
  ------------------------------
  Initialize NUT (see ...)

  Configure address of NUT by reboot (sequence parameter addrconf=boot)

  while waiting reboot (120[sec]) {
     Send DAD Packet to NUT to force NUT to detect address duplication.
     ==== Action #1: DAD NS ====>
           name: dadpkt_to_NUT

     Check if the DAD NS does not come from NUT
     (when NUT detect address duplication in random delaying phase).
     If DAD NS come, retry the test sequence.
     <=== Judgement #1: DAD NS does not come====
           name: dadns_from_NUT
           timeout: 2 [sec]  (2[sec] >= RandomDelay=0-1[sec] + RetransTimer=1[sec])
  }

  Check if NUT's address is not configured
  ==== Action #2: DAD NS ====>
        name: chkconf_dadns_to_NUT

  DAD NA does not come because NUT detect address duplicated and address is not configured.
  <=== Judgement #2: DAD NA does not come====
        name: chkconf_dadna_from_NUT (or chkconf_dadna_from_NUT_rf1 if NUT is a Router)
