The Point-to-Point Protocol (PPP) Data Link Layer [RFC1331][RFC1332][RFC1353] contains a 16 bit Protocol field to identify the the encapsulated protocol. The Protocol field is consistent with the ISO 3309 (HDLC) extension mechanism for Address fields. All Protocols MUST be assigned such that the least significant bit of the most significant octet equals "0", and the least significant bit of the least significant octet equals "1". It is recommended that values in the "02xx" to "1exx" and "xx01" to "xx1f" ranges not be assigned, as they are compression inefficient.

Expert Review
A one octet field is used in the Extensible Authentication Protocol (EAP) to indicate the function and structure of EAP Request and Response packets [RFC3748]. This registry has been replaced. See the "Method Types" registry at [IANA registry eap-numbers] for a current list of the assigned types.

PPP Vendor Extensions [RFC2153] uses IEEE standard OUIs (Organizationally Unique Identifiers) to indicate vendor-specific features. See [RFC1700] for details on contacting the IEEE. Vendors that desire to use their IEEE 802 OUI for PPP Vendor Extensions should register their OUI with IANA. Vendors that do not otherwise need an IEEE assigned OUI can request a PPP specific OUI from IANA out of the 'CF0000' range, which has both the "locally-assigned" and "broadcast/multicast" bits set to one. See [RFC2153] for details.

IPV6CP Configuration Options allow negotiation of desirable IPv6 parameters. IPV6CP uses the same Configuration Option format defined for LCP, with a separate set of Options. If a Configuration Option is not included in a Configure-Request packet, the default value for that Configuration Option is assumed.

The duplicate assignment of CF0001 was inadvertent. As per Expert Donald Eastlake, this assignment has been moved to here from the ethernet-numbers registry. |
