mld6query
— send
multicast listener query
mld6query |
[-dr ] intface
[maddr] |
mld6query
sends an IPv6 multicast listener
discovery (MLD) query packet toward the specified multicast address,
maddr, toward interface intface.
If you omit maddr, linklocal all nodes multicast
address(ff02::1) is used.
After sending a query, mld6query
waits for
replies for at most 10 seconds. If a reply is returned,
mld6query
prints it with its type and then waits for
another reply.
This program is provided only for debugging. It is not necessary for normal use.
With -d
, mld6query
will transmit MLD done packet instead of MLD query packet. With
-r
, similarly, MLD report packet will be
transmitted. -dr
options are for debugging purposes
only.
The mld6query
utility exits 0 on
success, and >0 if an error occurs.
The mld6query
command first appeared in
WIDE/KAME IPv6 protocol stack kit.
mld6query
does not take care of multicast
addresses which have non link-local scope.
