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  mul-
       ticast  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 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 multicast 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.

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

       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: Prints
       packet  warnings  to  stderr.   Prints  all level 1 messages and notifications of down networks to stderr.  Prints all level 2 messages and
       notifications of all packet timeouts to stderr.	Specifies the flooding option. Flooding allows the recursive search of neighboring  multi-
       cast  routers, and is enabled by default when starting_router is not used.  Specifies graphing in GraphEd format.  Disables the Domain Name
       Service (DNS) lookup for names of multicast routers.  Specifies the number of times to retry a neighbor query.  The  default  is  1  retry.
       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 speci-
       fied 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.
