NAME

       mrinfo - Multicast Routing Configuration Information Tool

SYNOPSIS

       debuglevel] retries] timeout] [ multicast-router ]

DESCRIPTION

       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.  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:

       If there are multiple neighbor routers on one interface, they will all be reported on the output.  The possible values for flag are:

       Neighbors are reached via tunnel.

       The tunnel uses IP source routing.

       The interface is down.

       The interface is administratively disabled for multicast routing.

       The local router is the querier of the subnet.

       Please see mrouted(1M) for and

       The command line options are:

       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.

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

       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 from the local routing daemon.
