map-mbone - Multicast connection mapper
/usr/sbin/map-mbone [ -d debug_level ] [ -f ] [ -g ] [ -n ] [ -r retry_count ] [ -t time-
out_count ] [ starting_router ]
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.
"-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:
packet warnings are printed to stderr.
all level 1 messages plus notifications down networks are printed to stderr.
all level 2 messages plus notifications of all packet timeouts are printed to
"-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.
map-mbone must be run as root.
