 NAME
      map-mbone - Multicast Router Connection Mapper

 SYNOPSIS
      /usr/sbin/map-mbone [-d debuglevel] [-f] [-g] [-n] [-r retries] [-t
      timeout] [ multicast-router ]

 DESCRIPTION
      map-mbone requests the multicast router connection information from
      the multicast-router, and prints the information to the standard out.
      map-mbone sends out the ASK_NEIGHBORS igmp message to the multicast-
      router.  When the multicast-router receives the request, it sends back
      its configuration information. multicast-router can be either an ip
      address or a system name.

      If the multicast-router is not specified, flood mode is on by default
      and the igmp request message is sent to all the multicast router on
      the local network. With flood mode on, when map-mbone finds new
      neighbor routers from the replies, it will send the same igmp request
      to the new neighbor routers. This activity continues until no new
      neighbor routers are reported in the replies.

      The command line options are:

	   -ddebuglevel	 Sets the level for printing out the debug message.
			 The default is 0, which prints only error and
			 warning messages. Debug level three prints most the
			 messages.

	   -rretries	 Sets the retry times to poll the routing daemon for
			 information. The default is 1.

	   -ttimeout	 It specifies the timeout value in seconds for
			 waiting the reply. The default value is 2 seconds.

	   -f		 Sets the flood mode on. It is the default value
			 when no multicast-router is given on the command
			 line input.

	   -g		 Generates output in GRaphEd format.

	   -n		 Disable DNS lookup for the multicast router names.

      The output contains the interface configuration information of  the
      requested router(s).  The format for each interface output is:

	   interface_addr ->&gt&gt> neighbor_addr (neighbor_name) [metrics/thresh/flags]

      If there are multiple neighbor routers on one interface, they will all
      be reported.  The neighbor_name will not be printed if the -n option
      is specified on the command line.

      The possible values for flags are:

	   tunnel	 Neighbors are reached via tunnel.

	   srcrt	 The tunnel uses IP source routing.

	   down		 The interface is down.

	   disabled	 The interface is administratively disabled for
			 multicast routing.

	   querier	 The local router is the querier of the subnet.

      The format of the GRaphEd output is:

	   interface_addr_in_integer {$ NP low_byte_addr high_byte_addr} node_name
	   [ neighbor_addr_in_integer metrics/threshold/flags ]

      If there is no neighbor router on an interface, then a * will be put
      next to the node_name. If there are multiple neighbor routers on one
      interface, all of them will be reported.	The possible values for
      flags are:

	   E	The neighbor is reached via tunnel.

	   P	     The neighbor is on the same network/subnet.

	   D	     The interface is down.

	   Please see mrouted(1M) for metrics and thresh.

 EXAMPLES
      Querying camden.cup.hp.com for the multicast router connection
      information.

	   map-mbone hpntclt.cup.hp.com

	     193.2.1.39 -> 0.0.0.0 (all-zeros-broadcast) [1/1/disabled]
	     15.13.106.144 -> 15.255.176.33 (matmos.hpl.hp.com) [10/1/tunnel]
	     15.13.106.144 -> 15.17.20.7 (hpspddc.vid.hp.com) [10/1/tunnel/down]

      Querying hpntcbs.cup.hp.com for multicast router connectivity with -g
      option:

	   map-mbone -g hpntcbs.cup.hp.com
