This document proposes extensions to IPv6 Neighbor Discovery for IPv6-over-(foo)-over-IPv4 links, where (foo) is either an encapsulating layer (e.g., UDP) or a NULL layer. It is essentially a lightweight, link-layer mechanism for neighbors to establish security associations, discover and dynamically re-adjust maximum receive unit (MRU) estimates, and perform unreachability detection. The protocol makes no attempt to ensure reliable message delivery; this function is performed by higher-layer protocols, e.g. TCP.
