Test sequence

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

  Send Unsolicited RA to configure address of NUT
  ==== Action #1: Unsolicited RA ===>
        name: usolra
        src: TN's Link-local address
        dst: allnodes multicast
        SLL option exists
        Prefix option
              PrefixLength: 64
              LFlag: 1
              AFlag: 1
              ValidLifetime: 90
              PreferredLifetime: 30
              Prefix: _GLOBAL0_UCAST_PRFX
        Prefix option
              PrefixLength: 64
              LFlag: 1
              AFlag: 1
              ValidLifetime: 120
              PreferredLifetime: 60
              Prefix: _GLOBAL1_UCAST_PRFX

  TN wait the DAD NS sends from NUT. (This judgement is informational only.)
  <=== Judgement #1-1: DAD NS ====
        name: dadns_from_NUT
        src: ::0
        dst: solnode[TargetAddress]
        TargetAddress: NUT's tentative _GLOBAL[01]_UCAST_PRFX + interface-id

  TN wait the DAD NS sends from NUT. (This judgement is informational only.)
  <=== Judgement #1-2: DAD NS ====
        name: dadns_from_NUT
        src: ::0
        dst: solnode[TargetAddress]
        TargetAddress: NUT's tentative _GLOBAL[01]_UCAST_PRFX + interface-id

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

  Wait <waitsec> [sec] to spent NUT's address lifetime.

  Execute ping on NUT by remote control
  ==== Action #2: execute "ping6 3ffe:501:ffff:102::1" ===>

  TN wait the ICMPv6 echo request send from NUT.
  <=== Judgement #2: ICMPv6 echo request ====
        name: echo_request
        src: <Source Address>
        dst: 3ffe:501:ffff:102::1

JUDGEMENT

Test for a Host

The following table shows RA for address configuration and address states by <waitsec>.

    Contents of RA (usolra)
   ------------------------------------------------------

     PreferredLifetime[sec]    30        60
     ValidLifetime[sec]        90       120
   ------------------------------------------------------

    Address states by waitsec
   ------------------------------------------------------
    <waitsec> [sec]      GLOBAL0 state  GLOBAL1 state
      10( 0-30)           valid pref    valid pref
