To set up a 6LoWPAN network, connect compatible IEEE 802.15.4 nodes, designate one node or host as the IPv6 border router, and configure the remaining nodes to join its routed network. The steps below use Contiki-NG as a concrete example; commands vary by board, radio, target and host operating system. First confirm your exact hardware is supported by the Contiki-NG release you plan to use.
Which nodes do I need?
6LoWPAN is an adaptation mechanism for carrying IPv6 over low-power IEEE 802.15.4 links. It handles the link constraints, including IPv6 header compression described in RFC 4944 and RFC 6282; it does not choose the routing protocol. In this example, RPL provides routing for the low-power network, as specified in RFC 6550.
- Border router: connects the 802.15.4 network to the host or another IPv6 network and acts as the RPL DAG root in the documented Contiki-NG arrangement.
- Network nodes: run an RPL-enabled application and join the border router’s network. They should not start a separate DAG.
- Host connection: in embedded mode, a serial SLIP connection and the host’s
tunslip6program connect the border router to a host TUN interface. Native mode instead runs the border-router stack on the host and uses a radio node runningslip-radio.
For a physical build, you will need compatible IEEE 802.15.4 development hardware. Do not assume a board or USB radio is supported because it uses that radio standard: check the Contiki-NG platform support documentation for the exact board, radio and release.
Choose embedded or native border-router mode
| Mode | Where the IPv6 border-router stack runs | Host connection and trade-off |
|---|---|---|
| Embedded | On a constrained network node programmed with the border-router example. | The host runs tunslip6 over serial and creates/configures a TUN interface. This uses the node’s resources for the border-router stack. |
| Native | On the host computer; a radio node runs slip-radio. |
This separates the radio/MAC side from the upper layers. Contiki-NG documents a TSCH schedule limitation when the schedule cannot be communicated to slip-radio; the arrangement is described as usable with CSMA or with TSCH using the 6TiSCH minimal schedule. |
The commands below describe Contiki-NG hardware setups, not universal 6LoWPAN commands. If your goal is a virtual test rather than actual radio connectivity, Contiki-NG points to a separate Cooja simulation tutorial.

How do I prepare the Contiki-NG nodes?
- Check your target: verify that your board and radio are supported for the selected Contiki-NG release, then choose embedded or native mode.
- Flash the border-router firmware: for embedded mode, build and program
examples/rpl-border-routerfor your target. - Flash the other nodes: program each with an RPL-enabled application, such as
hello-world. Ensure the application does not independently start another DAG; in this arrangement the border router starts the RPL DAG.
Build target names and programming steps depend on the platform. Use the target-specific instructions rather than copying a build command from a different board.
How do I connect an embedded border router to my computer?
Connect the programmed border-router node to the host over its serial interface. In the Contiki-NG tutorial, the embedded example is launched from the example directory with:

make TARGET=zoul connect-router
This example uses the zoul target and starts tunslip6 with a default serial path that includes /dev/ttyUSB0. Your device path may differ. If the default does not identify your node, run tunslip6 manually and give it the actual serial device with -s. The tutorial’s sample command is:
sudo ../../tools/serial-io/tunslip6 -s /dev/tty.usbmodemL1001111 fd00::1/64

Replace the sample device path with the one for your host and board. The command configures a TUN interface on the host and uses fd00::1/64 as the example host address and prefix. That is a configurable tutorial value, not a universal address plan; choose a prefix appropriate to your deployment. In the make-based setup, the prefix can be configured through the PREFIX variable.
How do I use native border-router mode instead?
- Program the radio node with Contiki-NG’s
slip-radiofirmware. - From the border-router example, build the host version with
make TARGET=native. - Run the resulting native border-router binary with the prefix you intend to use. Supply the correct serial device with
-sif it is not detected automatically.
In this mode, the host runs the border-router stack while the radio node handles the radio/MAC connection. Account for the documented TSCH schedule limitation: Contiki-NG describes native mode as usable with CSMA or with TSCH using the 6TiSCH minimal schedule when schedules cannot be communicated to slip-radio.

How do I verify the network?
- Check the border router’s output: read the IPv6 address it prints after startup.
- Ping the border router from the host: this checks basic reachability across the host connection.
- Inspect the border-router page: request its HTTP index page to view observed nodes, routes and links. Allow time for nodes to join and appear.
- Ping a joined node: use that node’s IPv6 address to verify connectivity beyond the border router.
These ping and HTTP checks are verification methods for the documented Contiki-NG implementation, not requirements imposed on every 6LoWPAN network. If a node is absent, check that it is powered, running an RPL-enabled application, using compatible hardware and link-layer settings, and has had time to join.
What should I check before using the setup beyond a lab?
- Confirm the supported board, radio, firmware target and host operating system for the precise Contiki-NG release you are using.
- Use the actual serial-device path for your system instead of assuming the tutorial’s example path.
- Plan an IPv6 prefix for the network; do not reuse
fd00::1/64automatically just because it appears in the tutorial. - Check link-layer schedule compatibility, particularly if using native mode with TSCH.
The documented setup establishes the roles, commands and verification flow for its example, but it does not establish one board, serial path, host command sequence or IPv6 prefix that is correct for every deployment. Consult the platform documentation for your release and adapt the target-specific details accordingly.
