| MAP-MBONE(8) | System Manager's Manual | MAP-MBONE(8) | 
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.
  
"-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.
