# NAME

      SrcSelectRule3.seq - Source Address Selection
                           check Rule 3(Avoid deprecated addresses)

      Rule 3: Avoid deprecated addresses.
        The addresses SA and SB have the same scope. If one of the two
        source addresses is "preferred" and one of them is "deprecated" (in
        the RFC 2462 sense), then prefer the one that is "preferred."

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

# SYNOPSIS

# 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 (deprecated / public ) in NUT
              * deprecated address is added by RA(PreferredLifetime=1) (TN->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 :
         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
