Hi Peter, The pledge sends packets with layer 2 address of the JP and layer 3 address set to link-local of *JP*. The packet mounts up to the CoAP layer on JP where it is forwarded to JRC.
This way, the pledge does not need to know the layer 3 address of the JRC. Hope that makes sense. I will make this clearer in the text.
