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.
