Overview. L2TP is one of the key building blocks for virtual private networks in the dial access space and is endorsed by Cisco and other internetworking industry leaders. It combines the best of Cisco's Layer 2 Forwarding (L2F) protocol and Microsoft's Point-to-Point Tunneling Protocol (PPTP).Tunneling Protocols :: Chapter 9: Cisco IOS IPSec Introduction :: Part ...

Tunneling Protocols. Most VPNs use the concept of tunneling to create a private network that extends across the Internet. Conceptually, it's as if a secure tunnel has been built between two end devices (routers, firewall, or VPN device). Data can be directed into one end of the tunnel and it travels securely to the other end.Layer 2 Tunneling Protocol - Wikipedia

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. Rather, it relies on an encryption protocol that it passes within the tunnel to provide ...How to configure GRE Tunnel on Cisco IOS Router | NetworkLessons ...

Apr 10, 2013 - We can tunnel these routing protocols so that the HQ and branch router can exchange routing information. Basically when you configure a tunnel, it's like you create a point-to-point connection between the two devices. GRE (Generic Routing Encapsulation) is a simple tunneling technique that can do this ...12-5 SSL VPNs & Tunneling Protocols - Free CCNA Study Guide
