ABSTRACT:
A network node unit and a method for forwarding data packets are provided. The network node unit is designed for forwarding data packets provided with a virtual network tag and comprises an identified cascading depth of the virtual network tag in the data packets which exceeds a predefined cascading depth, a filtered forwarding of data packets provided with a cascaded virtual network tag in accordance with the predefined and the identified cascading depth, and an administration table for entering the virtual network tag and address data of the data packets in accordance with the predefined and the identified cascading depth.
