The WG should produce one single document, not two. This is pretty simple stuff here and we don't need 2 documents, each only 5 pages long. Indeed, I think it's sort of unfortunate that we have started out with two competing documents, for no good reason that I can see. Its not like the proposed

I think 20 bits should be already be more than enough. For simplicity, I would just go for 64 bits. Assuming hosts generate sufficiently strong pseudo-random numbers, 20 bits means that once every one million cases of a genuine duplicate address, both hosts may mistakenly assume there is a

Hi, I was wondering...wouldn't the flow label be a "better" field for storing this random number? If i remember correctly, early drafts of RPL were using it for loop detection (ok, in a very different way), although in the later ones a new option was chosen.
