MAP-MBONE(8) BSD System Manager's Manual MAP-MBONE(8)NAMEmap-mbone - Multicast connection mapper
SYNOPSISmap-mbone [-d level] [-fgn] [-r count] [-t seconds] [starting_router]
DESCRIPTIONmap-mbone attempts to display all multicast routers that are reachable
from the multicast router starting_router. If not specified on the com-
mand line, starting_router is "localhost".
map-mbone sends an ASK_NEIGHBORS IGMP message to starting_router. A
response contains the multicast version number of starting_router and the
addresses of all its neighboring multicast routers. If the multicast ver-
sion number is recent, then map-mbone requests additional information
such as metrics, thresholds, and flags.
If a recursive search has been requested (see -f), map-mbone repeats the
above operation for each new multicast router in the list of neighbors
and continues the process until no new multicast routers are reported.
map-mbone must be run as root.
Options
-d level Sets the debug level to level. When the debug level is
greater than 0, additional debugging messages are printed to
stderr. 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 are
1: Print packet warnings, plus level 0 messages.
2: Print notifications of down networks, plus level 1
messages.
3: Print notifications of all packet timeouts, plus
level 2 messages.
Default is 0.
-f Causes a recursive (flooding) search. If no starting_router
is specified, a recursive search is always performed.
-g Sets graphing format to GraphEd format.
-n Disables DNS lookup for the names of the multicast routers.
-r count Sets the neighbor query retry limit to count. Default is 1.
-t seconds Sets the number of seconds to wait for a neighbor query reply
before retrying to seconds. Default is 2.
