Border routers are routers that can be found at the edge of a network. Their function is to connect one network to another. In this tutorial we will learn how to run a simulation using the border router in Contiki In the example which we will discuss in the rest of this tutorial the border router will be used to route data between a WSN (using RPL) and an external IP network.
