       map-mbone - Multicast connection mapper

SYNOPSIS    [Toc]    [Back]

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

OPTIONS    [Toc]    [Back]

       Sets the debug level. When the debug level is greater than
       0   (the   default),  additional  debugging  messages  are
       printed.  Regardless of  the  debug  level,  if  an  error
       occurs,  map-mbone writes an error message and terminates.
       Nonzero debug levels have the  following  effects:  Prints
       packet  warnings  to  stderr.  Prints all level 1 messages
       and notifications of down networks to stderr.  Prints  all
       level  2 messages and notifications of all packet timeouts
       to stderr.  Specifies the flooding option. Flooding allows
       the recursive search of neighboring multicast routers, and
       is enabled by default when starting_router  is  not  used.
       Specifies graphing in GraphEd format.  Disables the Domain
       Name Service (DNS) lookup for names of multicast  routers.
       Specifies  the  number of times to retry a neighbor query.
       The default is 1 retry.  Specifies the number  of  seconds
       to  wait  for a neighbor to reply to a query before retrying.
  The default timeout is 2 seconds.

DESCRIPTION    [Toc]    [Back]

       The map-mbone program displays information about 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 local host.

       The  map-mbone  program  traverses  neighboring  multicast
       routers by sending the ASK_NEIGHBORS IGMP message  to  the
       multicast   starting_router.   If  this  multicast  router
       responds, the response includes the version number  and  a
       list  of  addresses  of neighboring multicast routers.  If
       the responding router has a recent multicast version  number,
  map-mbone  requests  additional  information such as
       metrics,  thresholds,  and  options  from  the   multicast
       router.  If  the  flooding  option (-f) is specified, mapmbone
 asks each new neighboring  multicast  router  for  a
       list of neighbors.  This search for unique routers continues
  until  no  new  neighboring  multicast  routers   are
       reported.
