Synopsis
/usr/sbin/map-mbone
[ -d debug_level ]
[ -f ]

[ -n ]
[ -r retries ]
[ -t timeout ]
[ starting_router ]
Description
map-mbone attempts to display all multicast routers that are
reachable from the multicast starting_router. If not specified,
the default starting_router is the local host.
map-mbone traverses neighboring multicast routers by sending the
IGMP message ASK_NEIGHBORS to the multicast starting
router. If the router responds, it includes the version number
and a list of neighboring multicast router addresses in the response.
If the responding router has a recent multicast version number,
map-mbone requests additional information such as metrics,
thresholds and flags from the multicast router. If the flooding option has
been selected, map-mbone asks each multicast router mentioned in
the response for a list of its neighbors. This search for unique routers
continues until no new neighboring multicast routers are reported.
Only root can run map-mbone.
Options
map-mbone understands the following options:
-d debug_level-
Set the debug level. If debug_level is greater than the default
value of 0, map-mbone displays additional debugging messages.
Regardless of the debug level, map-mbone will always output an
error message and terminate if an error occurs. The debug levels are:
1-
Print packet warnings to stderr.
2-
As level 1 with the addition of printing notification of down networks to
stderr.
3-
As levels 1 and 2 with the addition of printing notification of all packet
timeouts to stderr.
-f-
Turn on ``flooding''; this allows recursive search of multicast
routes. This is enabled by default if a starting_router is not
specified.
-g-
Set graphing in GraphEd format.
-n-
Disable DNS for multicast router names.
-r retries-
Set the limit on the number of times to try querying a neighbor. The
default limit is 1 retry.
-t timeout-
Set the number of seconds to wait for a neighbor to reply to a query before
retrying. The default timeout is 2 seconds.
