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

Host only

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

 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 autoconfiguration

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

Test for host only

   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 #1: DAD NS =======
        name: DADNS_from_NUT

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

  ==== Action #1: RA =============>
        name: RA_LLA

  X<== Judgement #3: DAD NS =======
        name: DADNS_from_NUT

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

  Check if NUT's address is configured
  ==== Action #2: SOL NS =========>
        name: SOLNS_from_TN_GA0Tgt

  X<== Judgement #4: SOL NA =======
        name: 
              NA_from_NUT_GA0Tgt, 
              NA_from_NUT_GA0Tgt_woTLL,

              NA_from_GA0NUT_GA0Tgt_woTLL

JUDGEMENT

Test for Unicast address autoconfiguration

Test for host only

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: Link-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 SOL NS to check if NUT's address is configured.
        name: SOLNS_from_TN_GA0Tgt
        src: TN's Link-local
        dst: solnode[NUT's Global0]
        TargetAddress: NUT's Global0

   Judgement #4. NUT MUST NOT transmit SOL NA for its autoconfigured  Global address.
        name: 
              NA_from_NUT_GA0Tgt, 
              NA_from_NUT_GA0Tgt_woTLL, 
              NA_from_GA0NUT_GA0Tgt, 
              NA_from_GA0NUT_GA0Tgt_woTLL
        src: NUT's any Unicast Address
        dst: TN's Link-local
        TargetAddress: NUT's Global0
        RFlag: 0
        SFlag: 1
        OFlag: 1
        TLLOPT: NUT's MAC address
        (* TLLOPT may be omitted)
