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). Ele não fornece qualquer encriptação ou confidencialidade por si mesmo, em vez disso, ele conta com um
Ano ang L2TP (Layer 2 Tunneling Protocol)? Ang L2TP ay nakatayo para sa Layer 2 Tunneling Protocol, at ito – tulad ng ipinahihiwatig ng pangalan – isang tunneling protocol na idinisenyo upang suportahan ang mga koneksyon sa VPN. Nakatutuwang sapat, ang L2TP ay madalas na ginagamit ng mga ISP upang pahintulutan ang mga operasyon sa VPN. Ang L2TP ay unang nai-publish noong 1999.

Most often, the core technology of choice would be MPLS, but you can get similar results (although with more overhead and reduced traffic engineering capabilities) with IPSec-based Layer -3 VPNs and Layer 2 Tunneling Protocol Version 3 (L2TPv3)-based Layer 2 VPNs. Whatever you decide to offer your customers, be honest with them.
LAN Switching - Configuring Layer 2 Protocol Tunneling Layer 2 protocol tunneling allows Layer 2 protocol data units (PDUs) (CDP, STP, and VTP) to be tunneled through a network. This section uses the following terminology: • Edge switch—The switch connected to the customer switch and placed on the boundary of the service provider network (see Figure 21-1 ). Layer 2 Tunneling Protocol L2TP/IPSec VPN 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. L2TPv3 (Layer 2 Tunnel Protocol Version 3)
