RA_wPXLEN96 - check the process when NUT receives RA which contains one global prefix(PXLEN=96)(NOT Assigning Global address)

TARGET

All Node

SYNOPSIS

RA_wPXLEN96.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 RA which contains Global Prefix but its PrefixLength is 96,
   NUT MUST NOT assign autoconfigured address on Ethernet. 

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(Global) 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 Global Prefix.
        name: RA_GA0_PXLEN96
        src: TN's Link-local
        dst: allnode
        PXOPT: Global0
               PXLEN:96

   Judgement #3. NUT MUST NOT transmit DAD NS for its autoconfigured Global address.
                 (* If the address is consisits of EUI64, as same as Link-local
                 address, This DAD MAY be omitted.)
        name: DADNS_from_NUT_GA0Tgt
        src: ::0
        dst: solnode[NUT's tentative Global0]
        TargetAddress: NUT's tentative Global0

   Action #2. TN transmits DAD NS to check if NUT's address is configured.
        name: DADNS_from_TN_GA0Tgt
        src: ::0
        dst: solnode[NUT's Global0]
        TargetAddress: NUT's Global0

   Judgement #4. NUT MUST NOT transmit DAD NA for its autoconfigured  Global address.
        name: DADNA_from_NUT_GA0Tgt, DADNA_from_NUT_GA0Tgt_woTLL
        src: NUT's Link-local
        dst: allnode
        TargetAddress: NUT's Global0
        RFlag: 0
        SFlag: 0
        OFlag: 1
        TLLOPT: NUT's MAC address
        (* TLLOPT may be omitted)
