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.
