TARGET

Host and Router


SYNOPSIS

DADSendNS_DADPostSendNS.seq -pkt GLOBAL0A0N_ACAST.def addrconf=manual+_GLOBAL0A0N_ACAST init=DADSuccess_boot

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


INITIALIZATION

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


TEST PROCEDURE

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

  Configure address of NUT (addrconf=manual+_GLOBAL0A0N_ACAST, see Addrconf phase)

  TN wait the DAD NS sends from NUT
  <=== Judgement #1: DAD NS does not come====
        name: dadns_from_NUT

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

  Check if NUT's address is configured
  ==== Action #1: DAD NS ====>
        name: chkconf_dadns_to_NUT

  <=== Judgement #2: DAD NA ====
        name: chkconf_dadna_from_NUT (or chkconf_dadna_from_NUT_rf1 if NUT is a Router)


JUDGEMENT

   Judgement #1. DAD NS must not come from NUT on Anycast address configuration
        name: dadns_from_NUT
        src: ::0
        dst: solnode[NUT's tentative _GLOBAL0A0N_ACAST_ADDR]
        TargetAddress: NUT's tentative _GLOBAL0A0N_ACAST_ADDR

   Action #2. Send DAD NS to check if NUT's address is configured
        name: chkconf_dadns_to_NUT
        src: ::0
        dst: solnode[NUT's _GLOBAL0A0N_ACAST_ADDR]
        TargetAddress: NUT's _GLOBAL0A0N_ACAST_ADDR

   Judgement #2. DAD NA must come from NUT for Anycast address
        name: chkconf_dadna_from_NUT (or chkconf_dadna_from_NUT_rf1 if NUT is a Router)
        src: NUT's Link-local address (or Global address for router NUT)
        dst: allnodes multicast
        TargetAddress: NUT's _GLOBAL0A0N_ACAST_ADDR
        OFlag: 0 ( it should be 0 in NA of TargetAddress is an Anycast address )
        RFlag: 0 ( if NUT is a Router then 1)
