MAP-MBONE(8)            FreeBSD 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
       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.

INVOCATION
       "-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:

       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
       starting_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.
