NAME [Toc] [Back]
mrinfo - Multicast Routing Configuration Information Tool
SYNOPSIS [Toc] [Back]
/usr/sbin/mrinfo [-d debuglevel] [-r retries] [-t timeout]
[ multicast-router ]
DESCRIPTION [Toc] [Back]
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
interface_addr -> 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
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.
