NAME

LLA_DAD_NSPostDAD_wSLL - NUT receives invalid DAD NS (contains SLL)


TARGET

All Node


SYNOPSIS

LLA_DAD_NSPostDAD_wSLL.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

   NUT assignes autoconfigured address, even though NUT receives invalid 
   (contains SLL) DAD NS for same target address as NUT, while DAD process 
   (after transmitting 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_wSLL
  Wait for 5+DupAddrDetectTransmits*(RetransTimer/1000)[sec]
  Check if NUT's address is configured
  ==== Action #2: SOL NS =========>
        name: SOLNS_from_TN_SameTgt
  <=== 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 invalid DAD NS which contains SLL
        name: DADNS_from_TN_wSLL
        src: ::0
        dst: solnode[NUT's tentative Link-local]
        TargetAddress: NUT's Link-local
        SLLOPT: TN's MAC address
   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 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

NONE
