 # Nanostack Border Router
 Nanostack Border Router is a yotta module that provides the 6LoWPAN mesh network (1 RF interface) and backhaul network (1 backhaul interface) connectivity. It is a building block for 3rd party border router applications that implement their own backhaul driver or use some 3rd party driver.

 #### Configuring Nanostack Border Router
 Applications using the Nanostack Border Router should use a `config.json` file for configuration. The file should contain a   *border-router* section under which the Nanostack Border Router specific configuration options are defined. The complete list of all configuration options can be found in the [config.json.example](config.json.example) file.

 #### The routing protocol RPL
 Nanostack Border Router uses [RPL](https://tools.ietf.org/html/rfc6550) as the routing protocol on the mesh network side (RF interface). Currently, only the `grounded/non-storing` operation mode is supported.
