MAP-MBONE(8) System Manager's Manual MAP-MBONE(8) NAME map-mbone -- Multicast connection mapper SYNOPSIS map-mbone [-fgn] [-d level] [-r count] [-t seconds] [starting_router] DESCRIPTION map-mbone attempts to display all multicast routers that are reachable from the multicast router starting_router. If not specified on the command line, starting_router is "localhost". map-mbone must be run as root. 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 multi- cast version number is recent, then map-mbone requests additional in- formation 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 neigh- bors and continues the process until no new multicast routers are re- ported. The options are as follows: -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 condi- tion 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 re- ply before retrying to seconds. Default is 2.
