Protocolo l2tp rfc
The original pppol2tp driver was introduced in 2.6.23 and provided L2TPv2 functionality (rfc2661). L2TPv2 is used to tunnel one or more PPP sessions over a UDP tunnel. Layer 2 Tunneling Protocol (L2TP) is a computer networking protocol used by Internet service providers (ISPs) to enable virtual private network L2TP is similar to the Data Link Layer Protocol in the OSI reference model, but it is actually a session layer protocol. RFC 2661 "Layer Two Tunneling Protocol ’L2TP’" [RFC2661]. * For both IPv4 and IPv6 payloads (SPH), support is complete.

It documents kernel APIs for application developers who want to use the L2TP subsystem and it provides some This document describes the Layer Two Tunneling Protocol (L2TP). STD 51, RFC 1661 specifies multi-protocol access via PPP [RFC1661]. L2TP facilitates the tunneling of PPP packets across an intervening network in a way that is as transparent as possible to Download l2tp protocol rfc for FREE.

This document augments the procedures described in RFC 2661 to further support ATM SVC (Switched Virtual Circuits) or PVC (Permanent Virtual Circuits) based access networks. L2TP (Layer 2 Tunneling Protocol) specifies a protocol for tunnelling PPP packets over packet based networks and over IP networks in particular. El protocolo L2TP es una combinación de PPTP y L2F (protocolo propietario de Cisco). Utiliza UDP a través del puerto 1701 con dos tipos de paquetes: de transporte de tramas PPP y de control (creación, destrucción y mantenimiento del túnel).

Category: Standards Track Cisco Systems I. Goyret, Ed. Lucent Technologies March 2005 Layer Two Tunneling Protocol - Version 3 (L2TPv3… Publicado en 2000 como proyecto de norma RFC 2661, L2TP tiene su origen principalmente en dos protocolos de túnel de más edad para la comunicación punto a punto: Cisco 's protocolo de capa 2 Forwarding (L2F) y Microsoft ' s PPTP (PPTP). Una nueva versión de este protocolo, L2TPv3, apareció como el estándar propuesto RFC 3931 en 2005. 27/10/2003 Introduction [ RFC3931] defines a base protocol for Layer 2 Tunneling over IP networks.

[ RFC 2983 ] Black, D., "Differentiated Services and Tunnels", RFC 2983 , October 2000. L2TP (Layer 2 Tunneling Protocol) es un protocolo utilizado por redes privadas virtuales que fue diseñado por un grupo de trabajo de IETF como el heredero aparente de los protocolos PPTP y L2F, creado para corregir las deficiencias de estos protocolos y establecerse como un estándar aprobado por el IETF (RFC 2661). 1 Abstract Layer Two Tunneling Protocol (L2TP) describes a mechanism to tunnel Point-to-Point (PPP) sessions. The protocol has been designed to be independent of the media it runs over. The base specification describes how it should be implemented to run over the User Datagram Protocol (UDP) and the Internet Protocol (IP).

L2TP does not have integrated encryption, so this gets added via IPSec (Internet Protocol Security). L2TPv3 (Layer 2 Tunnel Protocol Version 3). Lesson Contents. Configuration.
