NAME

  SrcSelectRule6.seq - Source Address Selection
                       Check Rule 6(Prefer matching label)

  Rule 6: Prefer matching label. 
    If Label(SA) = Label(D) and Label(SB) <> Label(D), then prefer SA. 

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

TARGET

  Host and Router

SYNOPSIS

  SrcSelectRule6.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 : don't recive packet & check ping6 result
  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)

  *This test expected default policy table
  *Following address grouup does not match Rule 1-5

  Check 01:
    Destination: 2002:c0a8:2::2
    Candidate Source Addresses: 2002:c0a8:1::1 or 3ffe::1 or fec0::1 or LLA
    Result: 2002:c0a8:1::1

    If Label(2002:c0a8:1::1) = Label(2002:c0a8:2::2) and Label(3ffe::1) <> Label(2002:c0a8:2::2), then prefer 2002:c0a8:1::1. 

    If Label(2002:c0a8:1::1) = Label(2002:c0a8:2::2) and Label(fec0::1) <> Label(2002:c0a8:2::2), then prefer 2002:c0a8:1::1. 

JUDGEMENT

  Check 01:
    PASS: Receive Echo Request & source address = 2002:c0a8:1::1

  TEST
    PASS: All Check = PASS
