RFC 2661 - Layer Two Tunneling Protocol "L2TP" Abstract 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 both end-users and applications. L2TPv3 (Layer 2 Tunnel Protocol Version 3) L2TPv3 (Layer Two Tunneling Protocol Version 3) is a point-to-point layer two over IP tunnel. This means you can tunnel L2 protocols like Ethernet, Frame-relay, ATM, HDLC, PPP, etc. over an IP network. This can be pretty useful…For example, let’s say you have two remote sites and an application that requires that hosts are on the same subnet.

L2TP stands for Layer 2 Tunneling Protocol, and it doesn’t provide any encryption by itself. L2TP VPN usually uses an authentication protocol, IPSec (Internet Protocol Security), for strong encryption and authentication, which gives it an ultimate edge on some other most used protocols like PPTP. The L2TP protocol uses UDP ports 1701.

Layer 2 Tunneling Protocol (L2TP) is a computer networking protocol used by Internet service providers (ISPs) to enable virtual private network (VPN) operations. L2TP is similar to the Data Link Layer Protocol in the OSI reference model, but it is actually a session layer protocol. A User Datagram Protocol (UDP) port is used for L2TP

What can L2TP do for your network? | Network World The Layer 2 Tunneling Protocol (L2TP) is a standard protocol for tunneling L2 traffic over an IP network. Its ability to carry almost any L2 data format over IP or other L3 networks makes it
