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: Droms Expires November 17, 2014 [Page 2] Internet-Draft IPv6 Multicast Address Scopes May 2014 +------+--------------------------+ | scop | NAME | +------+--------------------------+ | 0 | reserved | | 1 | Interface | | 2 | Link-Local scope | | 3 | Realm-Local scope | | 4 | Admin-Local scope | | 5 | Site-Local scope | | 6 | (unassigned) | | 7 | (unassigned) | | 8 | Organization-Local scope | | 9 | (unassigned) | | A | (unassigned) | | B | (unassigned) | | C | (unassigned) | | D | (unassigned) | | E | Global scope | | F | reserved | +------+--------------------------+ The following change is applied to section 2.7 of RFC 4291: Droms Expires November 17, 2014 [Page 3] Internet-Draft IPv6 Multicast Address Scopes May 2014 OLD: 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.Show full document text
