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]

OPTIONS
  -d  Sets the debug level. When the debug level is greater than 0 (the
      default), additional debugging messages are printed.  Regardless of the
      debug level, if an error occurs, map-mbone writes an error message and
      terminates.  Nonzero debug levels have the following effects:

      1	  Prints packet warnings to stderr.

      2	  Prints all level 1 messages and notifications of down networks to
	  stderr.

      3	  Prints all level 2 messages and notifications of all packet
	  timeouts to stderr.

  -f  Specifies the flooding option. Flooding allows the recursive search of
      neighboring multicast routers, and is enabled by default when
      starting_router is not used.

  -g  Specifies graphing in GraphEd format.

  -n  Disables the Domain Name Service (DNS) lookup for names of multicast
      routers.

  -r retry_count
      Specifies the number of times to retry a neighbor query.	The default
      is 1 retry.

  -t timeout_count
      Specifies the number of seconds to wait for a neighbor to reply to a
      query before retrying.  The default timeout is 2 seconds.

DESCRIPTION
  The map-mbone program displays information about 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 local host.

  The map-mbone program traverses neighboring multicast routers by sending
  the ASK_NEIGHBORS IGMP message to the multicast starting_router.  If this
  multicast router responds, the response includes the version number and a
  list of addresses of neighboring multicast routers.  If the responding
  router has a recent multicast version number, map-mbone requests additional
  information such as metrics, thresholds, and options from the multicast
  router. If the flooding option (-f) is specified, map-mbone asks each new
  neighboring multicast router for a list of neighbors.	 This search for
  unique routers continues until no new neighboring multicast routers are
  reported.

RESTRICTIONS
  You must be superuser in order to run map-mbone.
