SrcSelectRule2.seq - Source Address Selection
Check Rule 2(Prefer appropriate scope)
Rule 2: Prefer appropriate scope.
If Scope(SA) < Scope(SB): If Scope(SA) < Scope(D), then prefer SB
and otherwise prefer SA.
Source addresses used for this test are "preferred address".
Host and Router
None
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
