hRouterMQueryOwn.seq - "Multicast Listener Discovery for IPv6" Test
Router send Multicast-Address-Specific Query (Own)
Host
None
This test check following, if node listen to Linklocal scope Multicast.
*1: A node transmit an Report message,
when a node receives a Multicast-Address-Specific Query message,
if it is listening to the queried Multicast Address.
-- in RFC2710 page 6 --
When a node receives a Multicast-Address-Specific Query, if it is
listening to the queried Multicast Address on the interface from
which the Query was received, it sets a delay timer for that address
to a random value selected from the range [0, Maximum Response
Delay], as above.
-- in RFC2710 page 6 --
-- in RFC2710 page 6 --
If a node's timer for a particular multicast address on a particular
interface expires, the node transmits a Report to that address via
that interface; the address being reported is carried in both the
IPv6 Destination Address field and the MLD Multicast Address field of
the Report packet. The IPv6 Hop Limit of 1 (as well as the presence
of a link-local IPv6 Source Address) prevent the packet from
traveling beyond the link to which the reporting interface is
attached.
-- in RFC2710 page 6 --
*2: NUT transmit an Report message within [Maximum Response Delay] ms.
-- in RFC2710 page 6 --
When a node receives a Multicast-Address-Specific Query, if it is
listening to the queried Multicast Address on the interface from
which the Query was received, it sets a delay timer for that address
to a random value selected from the range [0, Maximum Response
Delay], as above.

-Test flow
1. Listen to Multicast
1.1. Wait 1 or 2 Unsolicited Report message from NUT
Now Idle Listener state
2. TN send Multicast-Address-Specific Query message
(Maximum Response Delay = 700 ms
Multicast Address = NUT is listening to)
2.1. TN waits for a Report message for 700 ms
Check *1, *2
3. Stop to Listen Multicast
3.1. Wait Done message from NUT
NUT TN
