SrcSelectRule8.seq - Source Address Selection check Rule 8(Use longest matching prefix)
Rule 8: Use longest matching prefix. If CommonPrefixLen(SA, D) > CommonPrefixLen(SB, D), then prefer SA.
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. 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 : 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

*Following address grouup does not match Rule 1-7
Check 01: Destination: 3ffe:1234:1234:1234::2 Candidate Source Addresses: 3ffe:1234:1234:1234::1 or 3ffe:1234:1234:1235::1 or fec0::1 or LLA Result: 3ffe:1234:1234:1234::1
Check 02: Destination: 3ffe:1234:1234:1235::2 Candidate Source Addresses: 3ffe:1234:1234:1234::1 or 2001::1 or fec0::1 or LLA Result: 3ffe:1234:1234:1234::1
Check 01: PASS: Receive Echo Request & source address = 3ffe:1234:1234:1234::1
Check 02: PASS: Receive Echo Request & source address = 3ffe:1234:1234:1234::1
TEST PASS: Check 1 = PASS
