DstSelectExample6.seq - Destination Address Selection Examples in RFC
Check #6 (Avoid deprecated addresses)
Rule 3: Avoid deprecated addresses.
If Source(DA) is deprecated and Source(DB) is not, then prefer DB.
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)
2.2. TN send DNS query (answer)
2.3. NUT send ICMPv6 echo request
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 & in NUT
4.3. Remove DNS setting in NUT

Check 01:
DNS Address: 2001::9
Candidate Source Addresses: 2001::2 or fec0::NUT'sEUI64(deprecated) or LLA
Destination Address List: 2001::1 or fec0::1
Result: 2001::1 (src 2001::2) then fec0::1 (src fec0::NUT'sEUI64(deprecated))
* Use fec0::NUT'sEUI64 instead of fec0::1
Check 01:
PASS: Receive Echo Request & destination(source) = 3ffe::2(3ffe::1)
TEST
PASS: All Check = PASS
