MLD6QUERY(8)              BSD System Manager's Manual             MLD6QUERY(8)

NAME
     mld6query -- send multicast listener query

SYNOPSIS
     mld6query [-dr] intface [maddr]

DESCRIPTION
     The mld6query utility sends an IPv6 multicast listener discovery (MLD)
     query packet toward the specified multicast address, maddr, toward inter-
     face 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 sec-
     onds.  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.

RETURN VALUES
     The program exits with 0 on success, non-zero on failures.

HISTORY
     The mld6query utility first appeared in WIDE/KAME IPv6 protocol stack
     kit.

BUGS
     The mld6query utility does not take care of multicast addresses which
     have non link-local scope.
