NAME

LLA_DAD_NSPostDAD_Reserved - NUT receives valid DAD NS (Reserved Field).

TARGET

All Node

SYNOPSIS

LLA_DAD_NSPostDAD_Reserved.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 can properly ignore invalid neigbor solicitations while performing Duplicate Address Detection.

Test for Unicast address configuration

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

Test for all node

   When NUT performs DAD for its Link-local unicast address made by stateless
   address autoconfiguration, NUT receives DAD NS which contains same target as
   NUT's tentative Link-local address and Reserved Field==0xFFFFFFFF after 
   transimitting DAD NS.

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

  ==== Action #1: DAD NS =========>
        name: DADNS_from_TN_Reserved

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

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

  X<== Judgement #2: SOL NA =======
        name: NA_from_NUT, NA_from_NUT_woTLL

JUDGEMENT

Test for Link-local Unicast address autoconfiguration

Test for all NODE

NUT performs Stateless Address Autoconfiguration(Link-local) 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

   Action #1. TN transmits DAD NS which contains Reserved field 0xFFFFFFFF.
        name: DADNS_from_TN_Reserved
        src: ::0
        dst: solnode[NUT's tentative Link-local]
        Reserved: 0xFFFFFFFF
        TargetAddress: NUT's tentative Link-local

   Action #2. TN transmits SOL NS to check if NUT's address is configured.
        name: SOLNS_from_TN_SameTgt
        src: TN's Link-local
        dst: solnode[NUT's Link-local]
        TargetAddress: NUT's Link-local

   Judgement #2. NUT MUST NOT transmit SOL NA for its autoconfigured  Link-local address.
        name: NA_from_NUT, NA_from_NUT_woTLL
        src: NUT's Link-local
        dst: TN's Link-local
        TargetAddress: NUT's Link-local
        RFlag: 0 ( if NUT is a Router then 1)
        SFlag: 1
        OFlag: 1
        TLLOPT: NUT's MAC address

CLEANUP
