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
       multicast 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  mul-
       ticast  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. Re-
       gardless	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	start-
       ing_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.
