DESCRIPTION
requests the configuration information from the multicast-ourter, and

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

The the configuration information for each interface is printed in the
following format:
If there are multiple neighbor routers on one interface, they will all
be reported on the output. The possible values for flag are:
Neighbors are reached via tunnel.
The tunnel uses IP source routing.
The interface is down.
The interface is administratively disabled for multicast routing.
The local router is the querier of the subnet.
