NAME

v6LC_3_2_1_A - Unicast Autoconfigured Address - Global

TARGET

All Node

SYNOPSIS

v6LC_3_2_1_A.seq [-tooloption ...] -pkt <packetdef> [addrconf=<addrconfname>]

  -tooloption   : v6eval tool option
  <packetdef>   : packet definition file (v6eval tool option)
  <addrconfname>: how to configure address on NUT; boot/reboot

 detail of v6eval tool option: see perldoc V6evalTool.pm, perldoc V6evalRemote.pm

INITIALIZATION

 Reboot NUT or Initialize interface of NUT or Initialize IPv6 stack of NUT.

TEST PROCEDURE

Verify taht a node performs DAD on its autoconfigured unicast address.

Test for Unicast address configuration

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

Test for all node

   When NUT receives RA which contains Global Prefix, NUT assignes 
   autoconfigured address (or configures the Global address). 
   NUT must perform DAD for its Global address prior to assigning it.

Test sequence

  TN                            NUT
  ---------------------------------
  Initialize NUT

  Configure address of NUT (reboot or interface initialization etc...)

  TN wait the DAD NS sent from NUT
  <=== Judgement #1: DAD NS =======
        name: DADNS_from_NUT

  <=== Judgement #2: RS ===========
        name: RS_from_NUT, RS_from_NUT_wSLL

  ==== Action #1: RA =============>
        name: RA_GA0 (If NUT is a Router, configure a global address)

  <=== Judgement #3: DAD NS =======
        name: DADNS_from_NUT_GA0Tgt

  Wait for 5+DupAddrDetectTransmits*(RetransTimer/1000)[sec]

  Check if NUT's address is configured
  ==== Action #2: DAD NS =========>
        name: DADNS_from_TN_GA0Tgt

  <=== Judgement #4: DAD NA =======
        name: 
              DADNA_from_NUT_GA0Tgt, 
              DADNA_from_NUT_GA0Tgt_woTLL,

JUDGEMENT

Test for Global Unicast address autoconfiguration

Test for host only

NUT performs Stateless Address Autoconfiguration(Global) on its interface

   Judgement #1. NUT MUST transmit DAD NS for its autoconfigured Link-local address.
        name: DADNS_from_NUT
        src: ::0
        dst: solnode[NUT's tentative Link-local]
        TargetAddress: NUT's tentative Link-local

   Judgement #2. NUT SHOULD transmit RS.
        name: RS_from_NUT
        src: NUT's Link-local
        dst: allrouter

   Action #1. TN transmits RA which contains Global Prefix.
        name: RA_GA0
        src: TN's Link-local
        dst: allnode
        PXOPT: Global0

   Judgement #3. NUT MUST transmit DAD NS for its autoconfigured Global address.
        name: DADNS_from_NUT_GA0Tgt
        src: ::0
        dst: solnode[NUT's tentative Global0]
        TargetAddress: NUT's tentative Global0

   Action #2. TN transmits DAD NS to check if NUT's address is configured.
        name: DADNS_from_TN_GA0Tgt
        src: ::0
        dst: solnode[NUT's Global0]
        TargetAddress: NUT's Global0

   Judgement #4. NUT MUST transmit DAD NA for its autoconfigured  Global address.
        name: DADNA_from_NUT_GA0Tgt, DADNA_from_NUT_GA0Tgt_woTLL
        src: NUT's Link-local
        dst: allnode
        TargetAddress: NUT's Global0
        RFlag: 0
        SFlag: 0
        OFlag: 1
        TLLOPT: NUT's MAC address
        (* TLLOPT may be omitted)
