SrcSelectRule1.seq - Source Address Selection Check Rule 1(Prefer same address)
Rule 1: Prefer same address. If SA = 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 : 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

Check 01: Destination: 3ffe::1(GS) Candidate Source Addresses: 3ffe::1(GS) or fec0::1(SS) or LLA(LS) Result: 3ffe::1(GS)
Check 02: Destination: fec0::1(SS) Candidate Source Addresses: 3ffe::1(GS) or fec0::1(SS) or LLA(LS) Result: fec::1(SS)
Check 03: Destination: LLA(LS) Candidate Source Addresses: 3ffe::1(GS) or fec0::1(SS) or LLA(LS) Result: LLA(LS)
Check 01 - 03 PASS: Don't receive Echo Request and if possible, Please check source address in ping6 command result by your eyes
e.g. target5# /sbin/ping6 -n -c 1 -i 1 -h 64 -s 2 -p 00 -I ed0 3ffe::1 PATTERN: 0x00 PING6(50=40+8+2 bytes) 3ffe::1 --> 3ffe::1 ^^^^^^^ ^^^^^^^ if source address and destination adddress are equal, Check PASS
*Please rewrite the following file. tn.def : "RemoteLog 1"
TEST PASS: All Check = PASS
