1. Introduction
RFC 4291 [RFC4291] defines "scop" as "a 4-bit multicast scope value
used to limit the scope of the multicast group" and defines "scop 3"
as "reserved". The multicast protocol specification in [MPL] desires
to use multicast scop 3 to transport multicast traffic scoped to a
network of nodes connected in a mesh. This scop value is used to
accommodate a multicast scope that is greater than Link-Local but is
also automatically determined by the network architecture.
