Hello Alvaro 😊

I see your point. 

>    It is worth noting that with [RFC6550], every node in the LLN that is
>    RPL-aware can inject any RPL-based attack in the network.  This document
>    assumes that the security mechanisms as defined in [RFC6550] are followed.

This should be clarified a little bit. RPL has a security mechanism that to my best knowledge no one uses (https://tools.ietf.org/html/rfc6550#section-10).
What everyone uses is a Layer 2 access security. The text above seems to recommend to use RPL's secured mode. Is there a way to reword that a bit?

Take care,

Pascal
