This is the Contiki-NG border router. It supports two main modes of operation: embedded and native. In both cases, the border router runs a simple Web server that exposes a list of currently connected nodes via HTTP. See https://github.com/contiki-ng/contiki-ng/wiki/Tutorial:-RPL-border-router # Embedded border router The embedded border router runs on a node. It is connected to the host via SLIP. The host simply runs a tun gateway (`tunslip6`). To use, program a node, and then start `tunslip6` on the host via the make command `connect-router`. See embedded/README.md for more. # Native border router The native border router runs directly at the host. The node simply runs a SLIP-radio interface (`examples/slip-radio`). The host, on the other hand, runs a full 6LoWPAN stack. See native/README.md for more. # RPL node As RPL node, you may use any Contiki-NG example with RPL enabled, but which does not start its own DAG (as this is the responsibility of the border router). For instance `examples/hello-world` or `examples-coap` are great starting points. This is not intended to run with `examples/rpl-udp` however, as this examples builds its own stand-alone, border-router-free RPL network.
