Host

SYNOPSIS

ADDRCONFFail.seq -pkt LLOCAL_irregRA_prfxopt_ignore_llocal.def addrconf=ra init=DADFail_boot

INITIALIZATION

 detail of Initialization: see Test sequence for IPv6 Stateless Address Autoconfiguration.

TEST PROCEDURE

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

  Send Unsolicited RA to configure address of NUT (sequence parameter addrconf=ra)
  ==== Action #1: Unsolicited RA ===>
        name: usolra

  TN wait the DAD NS sends from NUT. (This judgment is informational only.)
  <=== Judgement #1: DAD NS ====
        name: dadns_from_NUT

  Wait for NUT to finish DAD. (sleep $RetransTimerSec [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's 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)

JUDGEMENT

   Action #1. Send irregular Unsolicited RA to configure address of NUT
        name: usolra
        src: TN's Link-local address
        dst: allnodes multicast
        SLL option exists
        Prefix option
              PrefixLength: 64
              LFlag: 1
              AFlag: 1
              ValidLifetime: 10000
              PreferredLifetime: 10000
              Prefix: _LLOCAL_UCAST_PRFX   (irregular, Link-local prefix is ignored)

   Judgement #1. DAD NS should come from NUT on Global address autoconfiguration.
                (This judgement is informational only.)
        name: dadns_from_NUT
        src: ::0
        dst: solnode[NUT's tentative _GLOBAL0_UCAST_PRFX + interface-id]
        TargetAddress: NUT's tentative _GLOBAL0_UCAST_PRFX + interface-id

   Action #2. Send DAD NS to check if NUT's address is not configured
        name: chkconf_dadns_to_NUT
        src: ::0
        dst: solnode[NUT's _GLOBAL0_UCAST_PRFX + interface-id]
        TargetAddress: NUT's _GLOBAL0_UCAST_PRFX + interface-id

   Judgement #2. DAD NA doesnot come from NUT because NUT's address is not configured.
        name: chkconf_dadna_from_NUT (or chkconf_dadna_from_NUT_rf1 if NUT is a Router)
        src: NUT's Link-local address or _GLOBAL0_UCAST_PRFX + interface-id
        dst: allnodes multicast
        TargetAddress: NUT's _GLOBAL0_UCAST_PRFX + interface-id
        OFlag: 1
        RFlag: 0 ( if NUT is a Router then 1)
