ABSTRACT:
In order to make the client host capable of learning an accounting information or an authentication failure information, the accounting information or the authentication failure reason is notified from the routing device2to the client host3, by adding an information regarding the accounting or an information regarding a reason for the authentication failure of the client host3, to a packet of a protocol based on IGMP or MLD which is a multicast control packet between the client host3and the router device2.
