MAP-MBONE(8)                                         MAP-MBONE(8)

       map-mbone - Multicast connection mapper

       /usr/sbin/map-mbone  [ -d debug_level ] [ -f ] [ -g ] [ -n
       ] [ -r  retry_count  ]  [  -t  timeout_count  ]  [  start-
       ing_router ]

       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 send-
       ing the ASK_NEIGHBORS IGMP message to the multicast start-
       ing_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,  thresh-
       olds,  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.

       "-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 net-
              works 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


MAP-MBONE(8)                                         MAP-MBONE(8)

       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.

       map-mbone must be run as root.
