     map-mbone - Multicast connection mapper

SYNOPSIS    [Toc]    [Back]

     map-mbone  [-d  level]  [-fgn]  [-r  count]   [-t   seconds]
[starting_router]

DESCRIPTION    [Toc]    [Back]

     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   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
     version 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.
