 The most common network parameters can be set on the docker command line. The default values are taken from the [Nordic Semiconductor border router](https://www.nordicsemi.com/Software-and-tools/Software/nRF5-SDK-for-Thread-and-Zigbee/Download#infotabs) such that it works with the examples in the [nRF5 SDK for Thread and Zigbee](https://www.nordicsemi.com/Software-and-tools/Software/nRF5-SDK-for-Thread-and-Zigbee).
 The command line options with default values are shown in the following table.
