MAP-MBONE(8) System Manager's Manual MAP-MBONE(8) NAME map-mbone - Multicast connection mapper SYNOPSIS /usr/sbin/map-mbone [ -d debug_level ] [ -f ] [ -g ] [ -n ] [ -r retry_count ] [ -t timeout_count ] [ starting_router ] DESCRIPTION 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 sending the ASK_NEIGHBORS IGMP message to the multicast starting_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, thresholds, and flags from the multicast router. For each new occurrence of neighboring mul- ticast 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. INVOCATION "-d" option sets the debug level. When the debug level is greater than the default value of 0, addition debugging messages are printed. Re- gardless 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: level 1 packet warnings are printed to stderr. level 2 all level 1 messages plus notifications down networks are printed to stderr. level 3 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 start- ing_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. IMPORTANT NOTE map-mbone must be run as root.
