IANA Allocation of Experimental Code Points for PIM Join Attribute and
PIM Encoded-Source Address

Abstract
This memo asks the IANA to allocate experimental code points to the
PIM Join Attribute Types register and the Encoded-Source Address
Encoding Type Field register.

1. 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.

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.
