MAP-MBONE(8)						      System Manager's Manual						      MAP-MBONE(8)

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 ]

DESCRIPTION

       map-mbone attempts to display all multicast routers that are reachable from the multicast starting_router.  If not specified on the command
       line, the default multicast starting_router is the localhost.

       map-mbone traverses neighboring multicast routers by sending the ASK_NEIGHBORS IGMP message to the multicast starting_router. If this  mul-
       ticast  router  responds,  the  version	number and a list of their neighboring multicast router addresses is part of that response. If the
       responding router has recent multicast version number, then map-mbone requests additional information  such  as	metrics,  thresholds,  and
       flags  from the multicast router. For each new occurrence of neighboring multicast router in the reply and provided the flooding option has
       been selected, then map-mbone asks each of this multicast router for a list of neighbors. This search  for  unique  routers  will  continue
       until no new neighboring multicast routers are reported.

INVOCATION

       "-d"  option  sets  the	debug level. When the debug level is greater than the default value of 0, addition debugging messages are printed.
       Regardless of the debug level, an error condition, will always write an error message and will  cause  map-mbone  to  terminate.   Non-zero
       debug levels have the following effects:

       level 1
	      packet warnings are printed to stderr.

       level 2
	      all level 1 messages plus notifications down networks are printed to stderr.

       level 3
	      all level 2 messages plus notifications of all packet timeouts are printed to stderr.

       "-f"  option  sets  flooding  option.  Flooding	allows the recursive search of neighboring multicast routers and is enable by default when
       starting_router is not used.

       "-g" option sets graphing in GraphEd format.

       "-n" option disables the DNS lookup for the multicast  routers names.

       "-r retry_count" sets the neighbor query retry limit. Default is 1 retry.

       "-t timeout_count" sets the number of seconds to wait for a neighbor query reply before retrying. Default timeout is 2 seconds.

IMPORTANT NOTE

       map-mbone must be run as root.
