map-mbone - Multicast connection mapper
/usr/sbin/map-mbone [ -d debug_level ] [ -f ] [ -g ] [ -n
] [ -r retry_count ] [ -t timeout_count ] [ start-
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 send-
ing the ASK_NEIGHBORS IGMP message to the multicast start-
ing_router. If this multicast 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, thresh-
olds, 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 net-
works are printed to stderr.
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
"-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
map-mbone must be run as root.
