Introduction To make it possible to experiment with protocol extensions safely, [RFC3692] recommends that "protocol documents should consider reserving a small set of protocol numbers for experimentation." Two IANA registries related to Protocol Independent Multicast (PIM) do not reserve any numbers for experimentation. This document requests the IANA to reserve two numbers for the Registry "PIM Join Attribute Types" and four numbers for the "Encoded-Source Address Encoding Type Field". 1.1. Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 2. Background In the Protocol Independent Multicast (PIM) Parameters [URL] Protocol Registry, two sub-registries have no allocation for either Private or Experimental use. They are "Encoded-Source Address Encoding Type Field", for which the current definitions are given in [RFC4601] and [RFC5384], and "PIM Join Attribute Types", for which the current definitions are given in [RFC5384]. For the Encoded-Source Address Encoding Type Field, two values area assigned, and the remainder (2-255) are unassigned. For the PIM Join Attribute Types, four values are assigned, and the remainder (4-63) are unassigned. Atwood & Venaas Expires September 4, 2014 [Page 2] Internet-Draft IANA Allocation of Experimental Code Points March 2014 The remaining sub-registries all have values assigned for Private Use, for Experimental Use, or for extension of the type space. The registrations proposed in this document are of type Experimental [RFC5226], because the expected usage of these reservations would not likely be confined to a single site. 3. Security Considerations This document only assigns values in two IANA registries. The security implications of the use of these values must be considered by those who make use of them. 4. IANA Considerations The requests in this document are for two registries that are part of the "Protocol Independent Multicast (PIM) Parameters" Registry. This document requests the IANA to reserve four values in the "Encoded-Source Address Encoding Type Field" registry: Type Name Reference ---- ---- --------- 251-255 Reserved (Experimental) [RFC4601][RFC5384][this doc] This document requests the IANA to reserve two values in the "PIM Join Attribute Types" registry: Type Name Reference ---- ---- --------- 64-65 Reserved (Experimental) [RFC5384][this doc] 5. Acknowledgements Adrian Farrel and Brian Haberman observed that there were no reservations for Experimental Use for the PIM Join Attribute Type. 6. References 6.1.
