Review result: Ready with Nits
The document defines a flag to mark NDP RA messages as originating from
an SNAC router.
As 6LoWPANs are likely to be typical stub networks, there may be relevant
IoT-related considerations in the broader context of SNAC, where this flag is
actually used. However, within the limited, "define-and-register" scope of
this document, I struggle to find an IoT angle. I guess topics like ND
optimisations/adaptations for 6LoWPANs, discussion on how constrained hosts on
the stub are protected from the infrastructure et similia will be tackled in
the main SNAC spec.
(RA-Guard is mentioned en-passant. Maybe worth discussing it in the security
considerations -- e.g., mentioning RFC7113?)
