NAME

  SrcSelectExample1.seq - Source Address Selection Examples in RFC
                          Check #1 - 4(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".

TARGET

  Host and Router

SYNOPSIS

  SrcSelectExample1.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 in 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: 2001::1 
    Candidate Source Addresses: 3ffe::1 or LLA
    Result: 3ffe::1

  Check 02:
    Destination: 2001::1 
    Candidate Source Addresses: LLA or fec0::1 
    Result: fec0::1

  Check 03:
    Destination: fec0::1 
    Candidate Source Addresses: LLA or 2001::1 
    Result: 2001::1

  Check 04:
    Destination: ff05::1 
    Candidate Source Addresses: LLA or fec0::1 or 2001::1 
    Result: fec0::1

    * Use LLA instead of fe80::1

JUDGEMENT

  Check 01:
    PASS: Receive Echo Request & source address = 3ffe::1

  Check 02:
    PASS: Receive Echo Request & source address = fec0::1

  Check 03:
    PASS: Receive Echo Request & source address = 2001::1

  Check 04:
    PASS: Receive Echo Request & source address = fec0::1

  TEST
    PASS: Check 1 = PASS
