IANA Considerations for the Point-to-Point Protocol (PPP)
Status of this Memo
This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements. Distribution of this memo is unlimited.

Abstract
The charter of the Point-to-Point Protocol (PPP) Extensions working
group (pppext) includes the responsibility to "actively advance PPP's
most useful extensions to full standard, while defending against
further enhancements of questionable value." In support of that
charter, the allocation of PPP protocol and other assigned numbers
will no longer be "first come first served."
Introduction
The Point-to-Point protocol (PPP, RFC 1661 [1]) is a mature protocol
with a large number of subprotocols, encapsulations and other
extensions. The main protocol as well as its extensions involve many
name spaces in which values must be assigned.
http://www.iana.org/assignments/ppp-numbers contains a list of the
address spaces and their current assignments.
Historically, initial values in new name spaces have often been
chosen in the RFCs creating the name spaces. The IANA made
subsequent assignments with a "First Come First Served" policy. This
memo changes that policy for some PPP address spaces.
Most of the PPP names spaces are quiescent, but some continue to
attract proposed extensions. Extensions of PPP have been defined in
RFCs that are "Informational" and so are not subject to review.
These extensions usually require values assigned in one or more of
the PPP name spaces. Making these allocations require "IETF
Consensus" will ensure that proposals are reviewed.

RFC 3818 IANA Considerations for PPP June 2004
Terminology
The terms "name space", "assigned value", and "registration" are used
here with the meanings defined in BCP 26 [2]. The policies "First
Come First Served" and "IETF Consensus" used here also have the
meanings defined in BCP 26.
IANA Considerations for PPP
IETF Consensus, usually through the Point-to-Point Protocol
Extensions working group (pppext), is required for assigning new
values in the following address spaces:
PPP DLL PROTOCOL NUMBERS
PPP LCP AND IPCP CODES
PPP LCP CONFIGURATION OPTION TYPES
PPP CCP CONFIGURATION OPTION TYPES
PPP CHAP AUTHENTICATION ALGORITHMS
PPP LCP FCS-ALTERNATIVES
PPP MULTILINK ENDPOINT DISCRIMINATOR CLASS
PPP LCP CALLBACK OPERATION FIELDS
PPP BRIDGING CONFIGURATION OPTION TYPES
PPP BRIDGING MAC TYPES
PPP BRIDGING SPANNING TREE
PPP IPCP CONFIGURATION OPTION TYPES
PPP IPV6CP CONFIGURATION OPTIONS
PPP IP-Compression-Protocol Types
Security Considerations
This memo deals with matters of process, not protocol.
