SrcSelectExample7.seq - Source Address Selection Examples in RFC
check #7(Use longest matching prefix)
Rule 8: Use longest matching prefix.
If CommonPrefixLen(SA, D) > CommonPrefixLen(SB, D), then prefer SA.
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. Add Candidate Source Addresses in NUT
1.3. 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

Check 01:
Destination: 2001::1
Candidate Source Addresses: 2001::2 or 3ffe::2

Check 01:
PASS: Receive Echo Request & source address = 2001::1
TEST
