Reviewer: Rich Salz Review result: Has Nits I reviewed this document for SECDIR. It's ready. I have one minor editorial suggestion. The introduction has this text: There are already link technology specific clarifications how to tune protocol constants for certain system with the expectation to reduce excess Neighbor Discovery Protocol (NDP) traffic. 3GPP cellular links are one existing example [RFC6459][RFC7066]. I would suggest rewording it like this: Clarifications for how to tune protocol constants to reduce Neighbord Discover Protocol (NDP) traffic already exist; for example [RFC6459] and ]RFC7066] for 3GPP.
