NAME

  DstSelectExample8.seq - Destination Address Selection Examples in RFC
                          Check #8(Prefer matching label)

  Rule 5: Prefer matching label. 
    If Label(Source(DA)) = Label(DA) and Label(Source(DB)) <> Label(DB), then prefer DA. 

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


TARGET

  Host and Router


SYNOPSIS

  DstSelectExample8.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. Set DNS setting in NUT
     1.3. Add Candidate Source Addresses in NUT
     1.4. Check Candidate Source Addresses by Ping6(TN->NUT)
  2. Send Ping6 from NUT to Destination(FQDN)
     2.1. NUT send DNS query (question)
     2.2. TN send DNS query (answer)
     2.3. NUT send ICMPv6 echo request
  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 & in NUT
     4.3. Remove DNS setting in NUT

  LLA(Link Local Address)

  Check 01:
    DNS Address: 2002:836b:4179::9
    Candidate Source Addresses: 2002:836b:4179::2 or LLA
    Destination Address List: 2002:836b:4179::1 or 2001::1
    Result: 2002:836b:4179::1 (src 2002:836b:4179::2) then 2001::1 (src 2002:836b:4179::2)

    * Use LLA instead of fe80::2


JUDGEMENT

  Check 01:
    PASS: Receive Echo Request & destination(source) = 2002:836b:4179::1(2002:836b:4179::2)

  TEST
    PASS: All Check = PASS
