PPP

This document defines two Huawei IPCP (IP Control Protocol) options used to convey a set of ports. These options can be used in the context of port range-based solutions or NAT-based solutions for port delegation and forwarding purposes. This document is not an Internet Standards Track specification; it is published for informational purposes.

The Point-to-Point Protocol (PPP) defines a Link Control Protocol (LCP) and a method for negotiating the use of multiprotocol traffic over point-to-point links. This document describes PPP support for the Transparent Interconnection of Lots of Links (TRILL) Protocol, allowing direct communication between Routing Bridges (RBridges) via PPP links. [STANDARDS-TRACK]

The Point-to-Point Protocol (PPP) provides a standard method of encapsulating network-layer protocol information over point-to-point links.

A pseudowire (PW) can be used to carry Point to Point Protocol (PPP) or High-Level Data Link Control (HDLC) Protocol Data Units over a Multiprotocol Label Switching (MPLS) network without terminating the PPP/HDLC protocol. This enables service providers to offer "emulated" HDLC, or PPP link services over existing MPLS networks. This document specifies the encapsulation of PPP/HDLC Packet Data Units (PDUs) within a pseudowire. [STANDARDS-TRACK]

This document defines two Extensible Authentication Protocol (EAP) extended key usage values and a public key certificate extension to carry Wireless LAN (WLAN) System Service identifiers (SSIDs). This document obsoletes RFC 3770. [STANDARDS-TRACK]

An IP device requires basic host configuration to be able to communicate. For example, it will typically require an IP address and the address of a DNS server. This information is configured statically or obtained dynamically using Dynamic Host Configuration Protocol (DHCP) or Point-to-Point Protocol/IP Control Protocol (PPP/IPCP). However, both DHCP and PPP/IPCP provide host configuration based on the access network. In Mobile IPv4, the registration process boots up a Mobile Node at an access network, also known as a foreign network. The information to configure the host needs to be based on the home network. This document describes the Cisco vendor-specific extensions to Mobile IPv4 to provide the base host configuration in Registration Request and Reply messages. This memo provides information for the Internet community.

The Layer Two Tunneling Protocol (L2TP) provides a method for tunneling PPP packets. This document describes an extension to L2TP, to make efficient use of L2TP tunnels within the context of deploying multicast services whose data will have to be conveyed by these tunnels. This memo defines an Experimental Protocol for the Internet community.

This document describes "version 3" of the Layer Two Tunneling Protocol (L2TPv3). L2TPv3 defines the base control protocol and encapsulation for tunneling multiple Layer 2 connections between two IP nodes. Additional documents detail the specifics for each data link type being emulated. [STANDARDS-TRACK]

This document defines the Extensible Authentication Protocol (EAP), an authentication framework which supports multiple authentication methods. EAP typically runs directly over data link layers such as Point-to-Point Protocol (PPP) or IEEE 802, without requiring IP. EAP provides its own support for duplicate elimination and retransmission, but is reliant on lower layer ordering guarantees. Fragmentation is not supported within EAP itself; however, individual EAP methods may support this. This document obsoletes RFC 2284. A summary of the changes between this document and RFC 2284 is available in Appendix A. [STANDARDS-TRACK]

The charter of the Point-to-Point Protocol (PPP) Extensions working group (pppext) includes the responsibility to "actively advance PPP's most useful extensions to full standard, while defending against further enhancements of questionable value." In support of that charter, the allocation of PPP protocol and other assigned numbers will no longer be "first come first served." This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements.

This document describes an option for negotiating the use of header compression on IP datagrams transmitted over the Point-to-Point Protocol (RFC 1661). It defines extensions to the PPP Control Protocols for IPv4 and IPv6 (RFC 1332, RFC 2472). Header compression may be applied to IPv4 and IPv6 datagrams in combination with TCP, UDP and RTP transport protocols as specified in RFC 2507, RFC 2508 and RFC 3545. [STANDARDS-TRACK]

This document describes a header compression scheme for point to point links with packet loss and long delays. It is based on Compressed Real-time Transport Protocol (CRTP), the IP/UDP/RTP header compression described in RFC 2508. CRTP does not perform well on such links: packet loss results in context corruption and due to the long delay, many more packets are discarded before the context is repaired. To correct the behavior of CRTP over such links, a few extensions to the protocol are specified here. The extensions aim to reduce context corruption by changing the way the compressor updates the context at the decompressor: updates are repeated and include updates to full and differential context parameters. With these extensions, CRTP performs well over links with packet loss, packet reordering and long delays. [STANDARDS-TRACK]

The Layer 2 Tunneling Protocol (L2TP) defines a mechanism for tunneling Point-to-Point Protocol (PPP) sessions. It is common for these PPP sessions to be established using modems connected over the public switched telephone network. One of the standards governing modem operation defines procedures that enable a client modem to put the call on hold and later, re-establish the modem link with minimal delay and without having to redial. While the modem call is on hold, the client phone line can be used to place or receive other calls. The L2TP base protocol does not provide any means to signal these events from the L2TP Access Controller (LAC), where the modem is physically connected, to the L2TP Network Server (LNS), where the PPP session is handled. This document describes a method to let the LNS know when a client modem connected to a LAC has placed the call on hold. [STANDARDS-TRACK]

The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP defines an extensible Link Control Protocol (LCP) and proposes a family of Network Control Protocols (NCP) for establishing and configuring different network-layer protocols. This document defines the NCP for establishing and configuring Remote Bridging for PPP links. This document obsoletes RFC 2878, which was based on the IEEE 802.1D- 1993 MAC Bridge. This document extends that specification by improving support for bridge control packets. [STANDARDS-TRACK]

This document defines extensions to the Layer Two Tunneling Protocol (L2TP) for enhanced support of link-specific Point to Point Protocol (PPP) options. PPP endpoints typically have direct access to the common physical media connecting them and thus have detailed knowledge about the media that is in use. When the L2TP is used, the two PPP peers are no longer directly connected over the same physical media. Instead, L2TP inserts a virtual connection over some or all of the PPP connection by tunneling PPP frames over a packet switched network such as IP. Under some conditions, an L2TP endpoint may need to negotiate PPP Link Control Protocol (LCP) options at a location which may not have access to all of the media information necessary for proper participation in the LCP negotiation. This document provides a mechanism for communicating desired LCP options between L2TP endpoints in advance of PPP LCP negotiation at the far end of an L2TP tunnel, as well as a mechanism for communicating the negotiated LCP options back to where the native PPP link resides.

Mobile IP [RFC 2002] defines media-independent procedures by which a Mobile Node can maintain existing transport and application-layer connections despite changing its point-of-attachment to the Internet and without changing its IP address. PPP [RFC 1661] provides a standard method for transporting multi-protocol packets over point-to-point links. As currently specified, Mobile IP Foreign Agents which support Mobile Node connections via PPP can do so only by first assigning unique addresses to those Mobile Nodes, defeating one of the primary advantages of Foreign Agents. This documents corrects this problem by defining the Mobile-IPv4 Configuration Option to the Internet Protocol Control Protocol (IPCP) [RFC 1332]. Using this option, two peers can communicate their support for Mobile IP during the IPCP phase of PPP. Familiarity with Mobile IP [RFC 2002], IPCP [RFC 1332], and PPP [RFC 1661] is assumed.
