NAME

mld6query – send multicast listener query

CONTENTS

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 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 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.
