In a method for exchanging routing messages in a wireless meshed communication network with network nodes and a root node, a routing tree is set up with data transmission paths. The root node sends routing requests at regular time intervals to set up the paths, wherein a request contains a specification for a first bidirectional path mode or a second unidirectional path mode. At a respective node, a first field is used to indicate a first or a second node state. If, upon receipt of a request, the first field is in the first state, a routing response is always sent and otherwise not. Next, the node checks the mode specified in the request, ensuring that the respective mode is set. In case of a node to root data transmission, a node also ensures that the first field of the respective network node is in the first state. |
