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 that 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", "assigned value", "registration". The following policies are used here with the meanings defined in BCP 26: "Private Use", "First Come First Served", "Expert Review", "Specification Required", "IETF Consensus", "Standards Action". 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]. Arberg Expires April 2006 [Page 2] Internet Draft draft-arberg-pppoe-iana-00.txt October 2005 2. IANA Considerations The PPPoE protocol as defined in [RFC2516] defines one name space that requires registration, the PPPoE TAG. 2.1 Recommended Registration Policies IANA needs to 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 point of contact MUST be provided for any assignment from this registry. If a specification description exists, a reference to this SHOULD also be provided. 2.2 Reserved PPPoE TAG Values TAG Value TAG Name Reference -------------- ------------------------- --------- 0 0x0000 End-Of-List [RFC2516] 257 0x0101 Service-Name [RFC2516] 258 0x0102 AC-Name [RFC2516] 259 0x0103 Host-Uniq [RFC2516] 260 0x0104 AC-Cookie [RFC2516] 261 0x0105 Vendor-Specific [RFC2516] 262 0x0106 Credits [BERRY] 263 0x0107 Metrics [BERRY] 264 0x0108 Sequence Number [BERRY] 272 0x0110 Relay-Session-Id [RFC2516] 273 0x0111 HURL [CARREL] 274 0x0112 MOTM [CARREL] 288 0x0120 PPP-Max-Payload [ARBERG] 289 0x0121 IP_Route_Add [CARREL] 513 0x0201 Service-Name-Error [RFC2516] 514 0x0202 AC-System-Error [RFC2516] 515 0x0203 Generic-Error [RFC2516] Arberg Expires April 2006 [Page 3] Internet Draft draft-arberg-pppoe-iana-00.txt October 2005 3.
