Abstract
The invention regards the forwarding of multicast messages in a network system. A network router according to the present invention comprises a memory in which configuration data is stored. The configuration data define at least one route along which a multicast message is to be forwarded. If the forwarding of a multicast message is allowed in principle by such specified route, it is additionally checked if from the downlink side of the network router, multicast listener information was received. Only if both conditions are fulfilled, the multicast message will be forwarded along the specified route.
