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

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
