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.
