NAME

  DstSelectRule10.seq - Destination Address Selection
                        Check Rule 10(Otherwise, leave the order unchanged)

  Rule 10: Otherwise, leave the order unchanged. 
    If DA preceded DB in the original list, prefer DA.

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


TARGET

  Host and Router


SYNOPSIS

  DstSelectRule10.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)

  *Following address grouup does not match Rule 1-9

  Check 01:
    DNS Address: 3ffe::9
    Candidate Source Addresses: 3ffe::1 or 2001::1 or fec0::1 or LLA
    Destination Address List: 3ffe::2 or 2001::2
    Result: 3ffe::2 (src 3ffe::1) then 2001::2 (src 2001::1)


JUDGEMENT

  Check 01:
    PASS: Receive ICMPv6 echo request &
          destination(source) = 3ffe::2(3ffe::1)

  TEST
    PASS: All Check = PASS
