A network node for a communication network comprising a first subnetwork and a second subnetwork connected to the first subnetwork, wherein the first subnetwork uses a spanning tree protocol and the second subnetwork uses a second protocol differing from the protocol of the first subnetwork, and the network node is configured as an element for the second subnetwork and is configured for communication within the second subnetwork. In addition, the network node configured by a spanning tree functionality as a spanning tree master node for checking and controlling the second subnetwork in such a way that the second subnetwork is handled or is able to be handled by the spanning tree protocol of the first subnetwork as a virtual network node.
