PPP Standards
(Page 2 of 3)

Base PPP Standards

Table 25 shows the “main” documents that describe PPP in general terms. They cover the basic operation of PPP including the PPP Link Control Protocol (LCP) and encapsulation of datagrams.

**Table 25: PPP Base Standards**
RFC Number	Standard Name	Description
1570	PPP LCP Extensions	Defines two new features for LCP that allow devices to identify each other to the other device and also tell the other device how much time remains in the current session.
1661	The Point-to-Point Protocol (PPP)	Base standard for the Point-to-Point protocol. Describes PPP architecture, general operation (including the process of link establishment, maintenance and termination) and details of the LCP protocol.
1662	PPP in HDLC-like Framing	Defines the specific framing method for PPP frames, based on that used in HDLC. This standard can be considered a “companion” to the main PPP standard, RFC 1661.

LCP Support Protocols

These protocols, shown in Table 26, support the basic operation of LCP. At this time the only protocols I put in this group are those that provide authentication services during link startup.

**Table 26: PPP LCP Support Protocol Standards**
RFC Number	Standard Name	Description
1334	PPP Authentication Protocols	Defines the two PPP authentication protocols: Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP). Note that RFC 1994 obsoletes RFC 1334, but does not discuss the PAP protocol. This basically tells you what the IETF thinks about PAP. J See the topic on PAP and CHAP for more on this.
1994	PPP Challenge Handshake Authentication Protocol (CHAP)	Updates the information about CHAP provided in RFC 1334.

Network Control Protocols (NCPs)

These are protocols that negotiate parameters specific to various layer three protocols carried over PPP. They are described in Table 27.

**Table 27: PPP Network Control Protocol Standards**
RFC Number	Standard Name	Description
1332	The PPP Internet Protocol Control Protocol (IPCP)	The NCP for the Internet Protocol (IP).
1377	The PPP OSI Network Layer Control Protocol (OSINLCP)	The NCP for OSI protocol suite network layer protocols, such as CNLP, ES-IS, and IS-IS.
1378	The PPP AppleTalk Control Protocol (ATCP)	The NCP for the AppleTalk protocol.
1552	The PPP Internetworking Packet Exchange Control Protocol (IPXCP)	The NCP for the Novell Internetworking Packet Exchange (IPX) protocol.
2043	The PPP SNA Control Protocol (SNACP)	The NCP for IBM's Systems Network Architecture (SNA).
2097	The PPP NetBIOS Frames Control Protocol (NBFCP)	The NCP for NetBIOS Frames (NBF, also commonly called NetBEUI).
2472	IP Version 6 over PPP	Describes the NCP for IPv6: the IPv6 Control Protocol (IPv6CP).
