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.

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.
