It doesn't help. But it does hinder if it isn't set. Suppose you have two stacks sharing the CoAP port on the same machine. You need to set IPV6_MULTICAST_LOOP so that the multicast queries you send get received by the other stack. That means you'll get your own discovery. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
