This document describes a Simplified Multicast Forwarding (SMF) mechanism
that provides basic Internet Protocol (IP) multicast forwarding suitable for limited wireless mesh and mobile ad
hoc network (MANET) use. It is mainly applicable in situations where efficient flooding represents an acceptable
engineering design trade-off. It defines techniques for multicast duplicate packet detection (DPD), to be applied in
the forwarding process, for both IPv4 and IPv6 protocol use. This document also specifies optional mechanisms
for using reduced relay sets to achieve more efficient multicast data distribution within a mesh topology
as compared to Classic Flooding. Interactions with other protocols, such as use of information provided by
concurrently running unicast routing protocols or interaction with other multicast protocols, as well as multiple deployment
approaches are also described. Distributed algorithms for selecting reduced relay sets and related discussion are provided
in the appendices. Basic issues relating to the operation of multicast MANET border routers are discussed,
but ongoing work remains in this area and is beyond the scope of this document.
This document defines an Experimental Protocol for the Internet community.
