DstSelectRule7.seq - Destination Address Selection
Check Rule 7(Prefer native transport)
Rule 7: Prefer native transport.
If DA is reached via an encapsulating transition mechanism (eg, IPv6
in IPv4) and DB is not, then prefer DB.
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 Configured Tunnel in NUT
1.2. Set static route (prefix(3ffe:1:1:1::) use Configured Tunnel) in NUT
1.3. Set IPv6 Default Route in NUT
(Default Router address = <TN-Link0-LinkLocalAddress>)
1.4. Set DNS setting in NUT
1.5. Add Candidate Source Addresses in NUT
1.6. 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 1-6
Check 01:
DNS Address: 2001::9
Candidate Source Addresses: 2001::1 or fec0::1 or fec0::1 or LLA
Destination Address List: 3ffe:1:1:1::2 or 3fff::2
Result: 3fff::2 (src 2001::1) then 3ffe:1:1:1::2 (src 2001::1)
Check 01:
PASS: Receive Echo Request & destination(source) = 3fff::2(2001::1)
TEST
PASS: All Check = PASS
