NAME
       map-mbone - Multicast connection mapper

SYNOPSIS
       /usr/sbin/map-mbone  [ -d debug_level ] [ -f ] [ -g ] [ -n ] [ -r retry_count ] [ -t time-
       out_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 start-
       ing_router is the localhost.

       map-mbone traverses neighboring multicast routers by sending the ASK_NEIGHBORS  IGMP  mes-
       sage to the multicast starting_router. If this multicast router responds, the version num-
       ber 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 mul-
       ticast 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.
