A network includes a first network participant connected via a first connection to a further network participant. The first network participant receives a data message containing information that a parameter must be set to a first value, via the first connection. The first network participant checks whether it is connected via a second connection to a still further network, and whether the parameter is not set to the first value in the second connection. In this case, the first network participant forwards the data message via the second connection, clearing down the second connection, and re-establishes the second connection, where the parameter for the second connection is set to the first value.
