SrcSelectExample9.seq - Source Address Selection Examples in RFC Check #9(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 "temporary address" and "public 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 privacy extention setting in NUT 1.3. Add Candidate Source Addresses (temporary / public ) in NUT * temporary address is added by RA (TN->NUT) 1.4. 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 4.3. Remove privacy extention setting in NUT

LLA(Link Local Address)
Check 01: Destination: 2002:836b:2179::1 Candidate Source Addresses: 2002:836b:2179::random(temporary) or 2001::2 Result: 2002:836b:2179::random (prefer matching label)
* Use 2002:836b:2179::random instead of 2002:836b:2179::d5e3:7953:13eb:22e8
Check 01: PASS: Receive Echo Request & source address != 2001::2 and LLA
TEST PASS: All Check = PASS
