DstSelectRule6.seq - Destination Address Selection Check Rule 6(Prefer matching label)
Rule 6: Prefer higher precedence. If Precedence(DA) > Precedence(DB), then prefer DA.
Source addresses used for this test are "preferred address".

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) (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

LLA(Link Local Address)
*This test expected default policy table *Following address grouup does not match Rule 1-5
Check 01: DNS Address: 3ffe::9 Candidate Source Addresses: 3ffe::1 or 2002:c0a8:1::1 or fec0::1 or LLA Destination Address List: 2002:c0a8:1::2 or 3ffe::2 Result: 3ffe::2 (src 3ffe::1) then 2002:c0a8:1::2 (src 2002:c0a8:1::1)
If Precedence(3ffe::2) > Precedence(2002:c0a8:1::2), then prefer 3ffe::2.
Check 01: PASS: Receive Echo Request & destination(source) = 3ffe::2(3ffe::1)
TEST PASS: All Check = PASS
