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 requires registration, the PPPoE TAG and the PPPoE Code field.
2.1 Registration Policies for PPPoE TAG Values
IANA shall 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.
2.2 Reserved PPPoE TAG Values
TAG Value TAG Name Tag Description Reference
----------- ------------------- ---------------------- ---------
0 0x0000 End-Of-List See the reference [RFC2516]
257 0x0101 Service-Name See the reference [RFC2516]

2.3 Registration Policies for PPPoE Code fields
IANA shall set up a registry of PPPoE Active Discovery Code
fields. These are 8-bit values. PPPoE Code fields already in use
are specified as reserved in this document, all other Code values
between 0 and 255 are to be assigned by IANA, using the
"First Come First Served" policy defined in [RFC2434].
A PPPoE Active Discovery packet 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.
2.4 Reserved PPPoE Code fields
Code PPPoE Packet Name Description Reference
-------- ------------------------------ ----------------- ---------
0 0x00 PPP Session Stage See the reference [RFC2516]
7 0x07 PADO, Offer See the reference [RFC2516]
9 0x09 PADI, Initiation See the reference [RFC2516]
10 0x0a PADG, Session-Grant See the reference [BERRY]
11 0x0b PADC, Session-Credit Response See the reference [BERRY]
12 0x0c PADQ, Quality See the reference [BERRY]
25 0x19 PADR, Request See the reference [RFC2516]
101 0x65 PADS, Session-confirmation See the reference [RFC2516]
167 0xa7 PADT, Terminate See the reference [RFC2516]
211 0xd3 PADM, Message See the reference [CARREL]
212 0xd4 PADN, Network See the reference [CARREL]
3. Security Considerations
This document focuses on IANA considerations for the PPPoE protocol,
and as such should help remove the possibility for the same PPPoE
code field and PPPoE TAG value being used for different
functionalities.
