L2F or Layer 2 Forwarding is a tunneling protocol developed by Cisco Systems. It is used to build virtual private networks (VPNs) over the internet that could in turn …

Layer Two Tunneling Protocol (L2TP) is an extension of the Point-to-Point Tunneling Protocol used by an Internet service provider to enable the operation of a virtual private network over the Internet. L2TP merges the best features of two other tunneling protocols: PPTP from Microsoft and L2F from Cisco Systems. Layer 2 Forwarding Protocol L2F , or Layer 2 Forwarding , is a protocol developed by Cisco to establish Virtual Private Network connections over the Internet. Virtual dial-up allows many separate and autonomous protocol domains to share common access infrastructure including modems, Access Servers, and ISDN routers. Jun 24, 2019 · L2TP is a successor to two other tunneling protocols: Cisco’s L2F and Microsoft’s PPTP. L2F is Layer 2 Forwarding Protocol and was part of the first generation of VPN protocols. However, it did not provide any encryption features by itself, and needed to be paired with PPP (Point-to-Point Protocol) to establish that encryption. L2TP (Layer 2 Tunneling Protocol) is the next good guy on our list to protect your data inside public networks and a merging of Microsoft's PPTP and Cisco's L2F (Layer 2 Forwarding) protocol. Contrary to OpenVPN, L2TP does not provide any encryption by itself and instead relies on a third party encryption protocol, the Internet Protocol PROTOCOLS.COM Mar 10, 2017 · L2TP is a tunneling protocol that does not inherently use any method of encryption. That is why it is normally encapsulated together with IPSec to provide some additional security. L2TP is an extension of the PPP protocol (like PPTP) and L2F. It is in many ways an improvement over PPTP and L2F. SSTP (Secure Socket Tunneling Protocol) is a newer VPN technology mostly supported by Windows Vista, Windows 7 and above.It’s no doubt the most amazing and most secure protocol for using VPN for countries that strong restricted internet like UAE((Iran,Oman,Saudi Arabia, etc) countries for it can bypass almost every government firewall on Port 443 that is difficult for many ISP’s to detect.

L2TP or Layer 2 Tunneling Protocol is an extension to the PPP protocol that merges the best features of two other tunneling protocols PPTP and L2F, and is used to support virtual private networks (VPNs).

Layer 2 Tunneling Protocol - Wikipedia Published in 2000 as proposed standard RFC 2661, L2TP has its origins primarily in two older tunneling protocols for point-to-point communication: Cisco's Layer 2 Forwarding Protocol (L2F) and Microsoft's Point-to-Point Tunneling Protocol (PPTP). A new version of this protocol, L2TPv3, appeared as proposed standard RFC 3931 in 2005.

L2F was designed by Cisco Systems (RFC 2341) to support the creation of secure VPDNs via tunnels over public infrastructure. The primary goal was (quoted from RFC 2341) "to divorce the location of the initial dial-up server from the location at which the dial-up protocol connection is terminated and access to the network provided." L2F (Layer Two Forwarding de Cisco) | Textos Científicos Concepto Protocolo desarrollado por Cisco, a diferencia del PPTP el protocolo L2F no depende de IP con lo cual es capaz de trabajar directamente bajo otros protocolos. Utiliza PPP para la autenticación de usuarios remotos. Los túneles que crea pueden soportar más de una conexión.
