MLD6QUERY(8) System Manager's Manual MLD6QUERY(8)
NAME
mld6querysend 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.
