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

NAME
       map-mbone -- Multicast connection mapper

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

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

       map-mbone  sends	 an  ASK_NEIGHBORS IGMP	message	to starting_router.  A
       response	contains the multicast version number of  starting_router  and
       the  addresses of all its neighboring multicast routers.	 If the	multi-
       cast version number is recent, then map-mbone requests  additional  in-
       formation 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	neigh-
       bors and	continues the process until no new multicast routers  are  re-
       ported.

       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	condi-
		   tion	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	messages.

			 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 re-
		   ply before retrying to seconds.  Default is 2.
