DstSelectRule2_deprecated.seq - Destination Address Selection
Check Rule 2(Prefer matching scopee) with deprecated address
Rule 2: Prefer matching scope.
If Scope(DA) = Scope(Source(DA)) and Scope(DB) <> Scope(Source(DB)), then prefer DA.
Source addresses used for this test are "preferred address" and "deprecated 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 (deprecated / public ) in NUT
* deprecated address is added by RA(PreferredLifetime=1) (TN->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)
Check 01:
DNS Address: 3ffe::9
Candidate Source Addresses: 3ffe::NUT'sEUI64(deprecated) or LLA
Destination Address List: fec0::2 or 3fff::2
Result: 3fff::2 (src 3ffe::NUT'sEUI64(deprecated)) then fec0::2 (src 3ffe::NUT'sEUI64(deprecated))
Scope(3fff::2) = Scope(3ffe::NUT'sEUI64) and Scope(fec0::2) <> Scope(3ffe::NUT'sEUI64), then prefer 3fff::2
Check 02:
DNS Address: fec0::9
Candidate Source Addresses: fec0::NUT'sEUI64(deprecated) or LLA
Destination Address List: 3fff::2 or fec0::2
Result: fec0::2 (src fec0::NUT'sEUI64(deprecated) then 3fff::2 (src fec0::NUT'sEUI64(deprecated))
Scope(fec0::2) = Scope(fec0::NUT'sEUI64) and Scope(3fff::2) <> Scope(fec0::NUT'sEUI64), then prefer fec0::2
Check 01:
PASS: Receive Echo Request & destination(source) = 3fff::2(3ffe::NUT'sEUI64(deprecated))
Check 02:
PASS: Receive Echo Request & destination(source) = fec0::2(fec0::NUT'sEUI64(deprecated))
TEST
PASS: All Check = PASS
