NAME

       mrinfo - Displays configuration information from a multicast router

SYNOPSIS

       /usr/sbin/mrinfo [-d debug_level] [-r retry_count] [-t timeout_count] multicast_router

OPTIONS

       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 condition occurs, mrinfo 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 number of times to retry a neighbor query.  The default  is  3  retries.
       Specifies the number of seconds to wait for a neighbor to reply to a query. The default timeout is 4 seconds.

DESCRIPTION

       The mrinfo command displays the configuration information from the multicast router multicast_router.

       The  mrinfo command sends the ASK_NEIGHBORS IGMP message to the specified multicast router.  If the multicast router responds, the response
       includes the version number and a list of addresses for their neighboring multicast routers.  If the responding router has a recent  multi-
       cast  version  number, mrinfo requests additional information such as metrics, thresholds, and options from the multicast router.  Once the
       specified multicast router responds, the configuration is displayed to the standard output.

RESTRICTIONS

       You must be superuser in order to run mrinfo.

EXAMPLES

       The following example shows the output of the mrinfo command where  mbone.phony.dom.net	is  specified  as  the	multicast  router:  mrinfo
       mbone.phony.dom.net 127.148.176.10 (mbone.phony.dom.net) [version 3.3]:
	127.148.176.10 -> 0.0.0.0 (?) [1/1/querier]
	127.148.176.10 -> 127.0.8.4 (mbone2.phony.dom.net) [1/45/tunnel]
	127.148.176.10 -> 105.1.41.9 (momoney.com) [1/32/tunnel/down]
	127.148.176.10 -> 143.192.152.119 (mbone.dipu.edu) [1/32/tunnel]

       For  each  neighbor of the queried multicast router, the IP address of the queried router is displayed, followed by the IP address and name
       of the neighbor. In square brackets, the metric (cost of connection) and the threshold (multicast ttl) are displayed. If the queried multi-
       cast router has a newer version number, the type (tunnel, srcrt) and status (disabled, down) of the connection are displayed.

NAME

       map-mbone - Multicast connection mapper

SYNOPSIS

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

DESCRIPTION

       map-mbone attempts to display 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 localhost.

       map-mbone traverses neighboring multicast routers by sending the ASK_NEIGHBORS IGMP message to the multicast starting_router. If this  mul-
       ticast  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.

INVOCATION

       "-d"  option  sets  the	debug level. When the debug level is greater than the default value of 0, addition debugging messages are printed.
       Regardless of the debug level, an error condition, will always write an error message and will  cause  map-mbone  to  terminate.   Non-zero
       debug levels have the following effects:

       level 1
	      packet warnings are printed to stderr.

       level 2
	      all level 1 messages plus notifications down networks are printed to stderr.

       level 3
	      all level 2 messages plus notifications of all packet timeouts are printed to stderr.

       "-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.

IMPORTANT NOTE

       map-mbone must be run as root.
