NAME

RA_wPXLLA - check the process when NUT receives invalid RA which contains one Link-local prefix(PX=LLA)(NOT Re-assigning Link-local address)

TARGET

All Node

SYNOPSIS

RA_wPXLLA.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

INITIALIZATION

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

TEST PROCEDURE

Test for Unicast address autoconfiguration

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

Test for all node

   When NUT receives invalid RA which contains Link-local Prefix,
   NUT MUST NOT assign autoconfigured address. 

Test sequence

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

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

  TN wait the DAD NS sent from NUT

JUDGEMENT

Test for Unicast address autoconfiguration

Test for all NODE

NUT performs Stateless Address Autoconfiguration 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 Link-local Prefix.
        name: RA_LLA
        src: TN's Link-local
        dst: allnode
        PXOPT: Linl-local

   Judgement #3. NUT MUST NOT transmit DAD NS for its autoconfigured Link-local address in this timing.
        name: DADNS_from_NUT
        src: ::0
        dst: solnode[NUT's tentative Link-local]
        TargetAddress: NUT's tentative Link-local

   Action #2. TN transmits DAD NS to check if NUT's Link-local address is still available.
        name: DADNS_from_TN_SameTgt
        src: ::0
        dst: solnode[NUT's Link-local]
        TargetAddress: NUT's Link-local

   Judgement #4. NUT MUST transmit DAD NA for its autoconfigured  Link-local address.
        name: DADNA_from_NUT
        src: NUT's Link-local
        dst: allnode
        TargetAddress: NUT's Link-local
        RFlag: 0
        SFlag: 0
        OFlag: 1
