SYNOPSIS
debuglevel] retries] timeout] [multicast-router]
DESCRIPTION
requests the multicast router connection information from the multi‐
cast-router, and prints the information to the standard out. sends out
the ASK_NEIGHBORS igmp message to the multicast-router. When the mul‐
ticast-router receives the request, it sends back its configuration
information. multicast-router can be either an ip address or a system
name.
If the multicast-router is not specified, flood mode is on by default
and the igmp request message is sent to all the multicast router on the
local network. With flood mode on, when finds new neighbor routers from
the replies, it will send the same igmp request to the new neighbor
routers. This activity continues until no new neighbor routers are
reported in the replies.
The command line options are:
Sets the level for printing out the debug message. The default
is 0,
which prints only error and warning messages.
Debug level three prints most the messages.
Sets the retry times to poll the routing daemon for information.
The
default is 1.
It specifies the timeout value in seconds for waiting the reply.
The
default value is 2 seconds.
Sets the flood mode on. It is the default value when no
multicast-router is given on the command line
input.
Generates output in GRaphEd format.
Disable DNS lookup for the multicast router names.
The output contains the interface configuration information of the
requested router(s). The format for each interface output is:
If there are multiple neighbor routers on one interface, they will all
be reported. The neighbor_name will not be printed if the option is
specified on the command line.
The possible values for are:
Neighbors are reached via tunnel.
The tunnel uses IP source routing.
The interface is down.
The interface is administratively disabled for multicast rout‐
ing.
The local router is the querier of the subnet.
The format of the GRaphEd output is:
If there is no neighbor router on an interface, then a will be put next
to the node_name. If there are multiple neighbor routers on one inter‐
face, all of them will be reported. The possible values for are:
The neighbor is reached via tunnel.
The neighbor is on the same network/subnet.
The interface is down.
