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
     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.

NAME

       map-mbone - Multicast connection mapper

SYNOPSIS

       /usr/sbin/map-mbone [-d debug_level] [-f] [-g] [-n] [-r retry_count] [-t timeout_count] [starting_router]

OPTIONS

       Sets  the  debug level. When the debug level is greater than 0 (the default), additional debugging messages are printed.  Regardless of the
       debug level, if an error occurs, map-mbone writes an error message and terminates.  Nonzero debug levels have the following effects: Prints
       packet  warnings  to  stderr.   Prints  all level 1 messages and notifications of down networks to stderr.  Prints all level 2 messages and
       notifications of all packet timeouts to stderr.	Specifies the flooding option. Flooding allows the recursive search of neighboring  multi-
       cast  routers, and is enabled by default when starting_router is not used.  Specifies graphing in GraphEd format.  Disables the Domain Name
       Service (DNS) lookup for names of multicast routers.  Specifies the number of times to retry a neighbor query.  The  default  is  1  retry.
       Specifies the number of seconds to wait for a neighbor to reply to a query before retrying.  The default timeout is 2 seconds.

DESCRIPTION

       The map-mbone program displays information about all multicast routers that are reachable from the multicast starting_router. If not speci-
       fied on the command line, the default multicast starting_router is the local host.

       The map-mbone program traverses neighboring multicast routers by sending the ASK_NEIGHBORS IGMP message to the  multicast  starting_router.
       If  this  multicast router responds, the response includes the version number and a list of addresses of neighboring multicast routers.	If
       the responding router has a recent multicast version number, map-mbone requests additional information such  as	metrics,  thresholds,  and
       options	from  the  multicast  router. If the flooding option (-f) is specified, map-mbone asks each new neighboring multicast router for a
       list of neighbors.  This search for unique routers continues until no new neighboring multicast routers are reported.

RESTRICTIONS

       You must be superuser in order to run map-mbone.
