DstSelectRule5.seq - Destination Address Selection
Check Rule 5(Prefer matching label)
Rule 5: Prefer matching label.
If Label(Source(DA)) = Label(DA) and Label(Source(DB)) <> Label(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 1-4
Check 01:
DNS Address: 2002:c0a8:1::9
Candidate Source Addresses: 2002:c0a8:1::1 or fec0::1 or LLA
Destination Address List: 2001::2 or 2002:c0a8:1::2
Result: 2002:c0a8:1::2 (src 2002:c0a8:1::1) then 2001::2 (src 2002:c0a8:1::1)
If Label(2002:c0a8:1::1) = Label(2002:c0a8:1::2) and Label(2002:c0a8:1::1) <> Label(2001::2), then prefer 2002:c0a8:1::2.
Check 01:
PASS: Receive Echo Request & destination(source) = 2002:c0a8:1::2(2002:c0a8:1::1)
TEST
PASS: All Check = PASS
