Router Affiliation Protocol for v6-over-(foo)-over-IPv4
Nokia
This document proposes a router affiliation protocol 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 nodes and routers to establish security associations, discover and dynamically re-adjust maximum transmission units, and detect router failures. The protocol makes no attempt to ensure reliable message delivery; this function is performed by higher-layer protocols, e.g. TCP.
