  TN wait the DAD NS sends from NUT. (This judgement is informational only.)
  <=== Judgement #1: DAD NS ====
        name: dadns_from_NUT
        src: ::0
        dst: solnode[TargetAddress]
        TargetAddress: NUT's tentative _GLOBAL0_UCAST_PRFX + interface-id

  Wait for NUT to finish DAD. (sleep $RetransTimerSec=1 [sec])

  permanent loop {
      Wait 30 [sec] to spent NUT's address lifetime.
      Count up totoal wait [sec] to spent NUT's address lifetime.

      Check if NUT's address is configured.
      ==== Action #2: DAD NS ====>
        name: chkconf_dadns_to_NUT
        src: ::0
        dst: solnode[TargetAddress]
        TargetAddress: NUT's _GLOBAL0_UCAST_PRFX + interface-id

      Check if DAD NA come from NUT (check if NUT's address configured)
      if DAD NA doesn't come, exit the permanent loop.
      <=== Judgement #2: DAD NA come====
        name: chkconf_dadna_from_NUT (or chkconf_dadna_from_NUT_rf1 if NUT is a Router)
