map-mbone - Multicast connection mapper
/usr/sbin/map-mbone [-d debug_level] [-f] [-g] [-n] [-r
retry_count] [-t timeout_count] [starting_router]
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 multicast 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.
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, mapmbone
asks each new neighboring multicast router for a
list of neighbors. This search for unique routers continues
until no new neighboring multicast routers are
You must be superuser in order to run map-mbone.
