1. Introduction
RFC 4291 [RFC4291] defines "scop is a 4-bit multicast scope value
used to limit the scope of the multicast group." scop 3 is defined as
"reserved" in RFC 4291. The multicast protocol specification in
draft-ietf-roll-trickle-mcast [I-D.ietf-roll-trickle-mcast] desires
to use multicast scop 3 for transport of multicast traffic scoped to
a network of nodes connected in a mesh. The use of this scop value
is to accommodate a multicast scope that is greater than Link-Local
but is also automatically determined by the network architecture.
2. Definition of IPv6 Multicast Address Scopes (Updates RFC 4291)
The following table updates the definitions in RFC 4291:

Admin-Local scope is the smallest scope that must be
administratively configured, i.e., not automatically derived
from physical connectivity or other, non-multicast-related
configuration.
