NAME

LLA_DADSuccess - check normal DAD process that should succeed

TARGET

All Node

SYNOPSIS

LLA_DADSuccess.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

Test for Unicast address configuration

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

Test for all node

   NUT performs DAD for its Link-local unicast address made by stateless address autoconfiguration.

Test sequence

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

  NUT configures address (reboot or interface initialization etc...)

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

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

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

  <=== Judgement #2: DAD NA =======
        name: DADNA_from_NUT

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 to check if NUT's address is configured
        name: DADNS_from_TN
        src: ::0
        dst: solnode[NUT's Link-local]
        TargetAddress: NUT's Link-local

   Judgement #2. NUT MUST transmit DAD NA for its autoconfigured  Link-local address.
        name: DADNA_from_NUT, DADNA_from_NUT_woTLL
        src: NUT's Link-local
        dst: allnode
        TargetAddress: NUT's Link-local
        RFlag: 0 ( if NUT is a Router then 1)
        SFlag: 0
        OFlag: 1
        TLLOPT: NUT's MAC address
