NAME
mld6query —
send multicast listener
query
SYNOPSIS
mld6query |
[-dr]
intface
[maddr] |
DESCRIPTION
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.
EXIT STATUS
The program exits 0 on success, and >0 on failures.
HISTORY
The
mld6query command first appeared in WIDE/KAME IPv6
protocol stack kit.
BUGS
mld6query does not take care of multicast addresses which have
non link-local scope.
