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
