     map-mbone -- Multicast connection mapper

     map-mbone [-fgn] [-d level] [-r count] [-t	seconds] [starting_router]

     map-mbone attempts	to display all multicast routers that are reachable
     from the multicast	router starting_router.	 If not	specified on the com-
     mand line,	starting_router	is "localhost".	 map-mbone must	be run as

     map-mbone sends an	ASK_NEIGHBORS IGMP message to starting_router.	A re-
     sponse contains the multicast version number of starting_router and the
     addresses of all its neighboring multicast	routers.  If the multicast
     version number is recent, then map-mbone requests additional information
     such as metrics, thresholds, and flags.

     If	a recursive search has been requested (see -f),	map-mbone repeats the
     above operation for each new multicast router in the list of neighbors
     and continues the process until no	new multicast routers are reported.

     The options are as	follows:

     -d	level	 Sets the debug	level to level.	 When the debug	level is
		 greater than 0, additional debugging messages are printed to
		 stderr.  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 are:

		       1.   Print packet warnings, plus	level 0	messages.

		       2.   Print notifications	of down	networks, plus level 1

		       3.   Print notifications	of all packet timeouts,	plus
			    level 2 messages.

		 Default is 0.

     -f		 Causes	a recursive (flooding) search.	If no starting_router
		 is specified, a recursive search is always performed.

     -g		 Sets graphing format to GraphEd format.

     -n		 Disables DNS lookup for the names of the multicast routers.

     -r	count	 Sets the neighbor query retry limit to	count.	Default	is 1.

     -t	seconds	 Sets the number of seconds to wait for	a neighbor query reply
		 before	retrying to seconds.  Default is 2.
