NAME

  SrcSelectExample6.seq - Source Address Selection Examples in RFC
                          Check #6(Prefer appropriate scope)

  Rule 2: Prefer appropriate scope. 
    If Scope(SA) < Scope(SB): If Scope(SA) < Scope(D), then prefer SB 
    and otherwise prefer SA. 

  Source addresses used for this test are "preferred address" and "deprecated address".

TARGET

  Host

SYNOPSIS

  SrcSelectExample6.seq [-tooloption ...] -pkt ADDR_SELECT.def
    -tooloption : v6eval tool option

INITIALIZATION

  None

TEST PROCEDURE

  This TEST performs the following Check procedures for
  every address group defined by Check 01 - *.
    
  *Check procedure
  
  1. Initialize :
     1.1. Set IPv6 Default Route in NUT
          (Default Router address = <TN-Link0-LinkLocalAddress>)
     1.2. Add Candidate Source Addresses (deprecated / public ) in NUT
          * deprecated address is added by RA(PreferredLifetime=1) (TN->NUT)
     1.3. Check Candidate Source Addresses by Ping6 (TN->NUT)
  2. Send Ping6 from NUT to Destination
     2.1. NUT send ICMPv6 echo request (NUT->TN)
  3. Judgment :
     if (recive packet's Destination & Source Addresses)
     = (expected Destination & Source Addresses), Check pass
  4. Cleanup :
     4.1. Delete Candidate Source Addresses in NUT
     4.2. Clear prefix list & NCE & default router list in NUT

  LLA(Link Local Address)

  Check 01:
    Destination: fec0::1 
    Candidate Source Addresses: fec0::NUT'sEUI64(deprecated) or 2001::1 
    Result: fec0::NUT'sEUI64(deprecated)

    * Use fec0::NUT'sEUI64 instead of fec0::2

JUDGEMENT

  Check 01:
    PASS: Receive Echo Request & source address = fec0::NUT'sEUI64(deprecated)

  TEST
    PASS: All Check = PASS
