# NAME

      DstSelectRule2_deprecated.seq - Destination Address Selection
                                      Check Rule 2(Prefer matching scopee) with deprecated address

      Rule 2: Prefer matching scope.
        If Scope(DA) = Scope(Source(DA)) and Scope(DB) <> Scope(Source(DB)), then prefer DA.

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

# TARGET

      Host

# SYNOPSIS

      DstSelectRule2_deprecated.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 (deprecated / public ) in NUT
              * deprecated address is added by RA(PreferredLifetime=1) (TN->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) (NUT->TN)
         2.2. TN send DNS query (answer) (TN->NUT)
         2.3. 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
         4.3. Remove DNS setting in NUT

        Destination Address List: fec0::2 or 3fff::2

# JUDGEMENT
