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 -> 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.
EXAMPLE
The following is an example of quering the multicasting configuration from the local routing daemon.
