RFC 4937             IANA Considerations for PPPoE             June 2007

1.  Introduction

   This document provides guidance to the Internet Assigned Numbers
   Authority (IANA) regarding the registration of values related to the
   PPP over Ethernet Protocol (PPPoE), defined in [RFC2516], in
   accordance with BCP 26, [RFC2434].  It also reserves PPPoE TAG values
   as well as PPPoE packet Code fields, which are or have been in use on
   the Internet.

1.1.  Terminology

   The following terms are used here with the meanings defined in BCP
   26:  "name space", "registration".

   The following policies are used here with the meanings defined in BCP
   26: "First Come First Served".

1.2.  Specification of Requirements

   In this document, several words are used to signify the requirements
   of the specification.  These words are often capitalized.  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 [RFC2119].

2.  IANA Considerations

   The PPPoE protocol, as defined in [RFC2516], defines two name spaces
   that require registration, the PPPoE TAG and the PPPoE Code field.

2.1.  Registration Policies for PPPoE TAG Values

   IANA has set up a registry of "PPPoE TAG Values".  These are 16-bit
   values.  PPPoE TAG values already in use are specified as reserved in
   this document.  All other TAG values between 0 and 65535 are to be
   assigned by IANA, using the "First Come First Served" policy defined
   in [RFC2434].

   A TAG-Name and a description for the usage, as well as a point of
   contact, MUST be provided for any assignment from this registry.  A
   document reference SHOULD also be provided.
