 NAME
      mrinfo - Multicast Routing Configuration Information Tool

 SYNOPSIS
      /usr/sbin/mrinfo [-d debuglevel] [-r retries] [-t timeout]
      [ multicast-router ]

 DESCRIPTION
      mrinfo requests the configuration information from the multicast-
      ourter, and prints the information to the standard out.  multicast-
      router can be either an IP address or a system name.  mrinfo sends out
      the ASK_NEIGHBORS igmp message to the specified multicast-router, when
      the router receives the request, it sends back its configuration
      information. If the multicast-router is not specified, the request is
      sent the local router.

      The the configuration information for each interface is printed in the
      following format:

	   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 on the output. The possible values for flag 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.

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

      The command line options are:

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

      -rretries	    Sets the retry times to pull the routing daemon for
		    information. The default is 3.

      -ttimeout	    Specifies the timeout value in seconds for waiting the
		    reply. The default value is 4.

      The following is an example of quering the multicasting configuration
