In computer networking, Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself; it relies on an encryption protocol that it passes within the tunnel to provide privacy.
I am planning to rename this page to "Layer 2 Tunneling Protocol", as this is the correct title. Any comments? Web-Crawling Stickler 18:52, 8 March 2007 (UTC) Which OSI model layer?? I have a book that says L2TP resides in the data-link layer (layer 2) of the OSI. Than this page says its in the session (layer 5) layer. RFC 3931 - Layer Two Tunneling Protocol - Version 3 (L2TPv3) Introduction The Layer Two Tunneling Protocol (L2TP) provides a dynamic mechanism for tunneling Layer 2 (L2) "circuits" across a packet-oriented data network (e.g., over IP). L2TP, as originally defined in RFC 2661 , is a standard method for tunneling Point-to-Point Protocol (PPP) [ RFC1661 ] sessions. L2TP MDM settings for Apple devices - Apple Support L2TP MDM settings for Apple devices. You can configure an L2TP VPN connection for Apple devices enrolled in a mobile device management (MDM) solution. If you have this type of VPN server, choose Layer 2 Tunneling Protocol (L2TP) so your Apple devices can use this method for connecting to … Buy L2TP Vpn For Windows,Mac,Ubunto And Iphone Devices Layer 2 Tunneling Protocol abbreviated as L2TP is a protocol commonly used by VPN service providers. L2TP doesn’t provide any authentication itself but uses an authentication protocol known as IPSec (Internet Protocol Security). This gives the VPN strong encryption for its connections.

Em rede de computadores, Layer 2 Tunnelling Protocol (L2TP), em português Protocolo de Tunelamento de Camada 2, é um protocolo de tunelamento usado para suportar redes virtuais privadas (VPNs) ou como parte da entrega de serviços pelos provedores de serviços de internet (ISPs).

[MS-L2TPIE]: Layer 2 Tunneling Protocol (L2TP) IPsec Extensions. 2/14/2019; 4 minutes to read; In this article. Specifies the Layer 2 Tunneling Protocol (L2TP) IPsec Extensions, which allows IP, IPX, or NetBEUI traffic to be encrypted and then sent over any medium that supports point-to-point (PPP) (Point to Point Protocol [RFC1661]) datagram delivery, such as IP, X.25, Frame Relay, or ATM.

Apr 16, 2018 layer2 - Is L2TP really a Layer 2 protocol? - Network Tunneling protocols like L2TP, GRE, IPSEC and MPLS don't fit well into the OSI model. L2TP tunnels (encapsulates) L2 frames in UDP so it can be transported over layer 3.
