# 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

# SYNOPSIS

      SrcSelectRule6.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. 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

      *Following address grouup does not match Rule 1-5

      Check 01:

        Candidate Source Addresses: 2002:c0a8:1::1 or 3ffe::1 or fec0::1 or LLA
        Result: 2002:c0a8:1::1

# JUDGEMENT

      Check 01:
        PASS: Receive Echo Request & source address = 2002:c0a8:1::1
