L2TP (Layer 2 Tunneling Protocol) is a tunneling protocol used to support VPNs. It doesn’t provide any encryption or
confidentiality by itself; it relies on an encryption protocol that it passes within the tunnel to provide privacy.
L2TP allows a PPP session to travel over multiple links and networks. PPP is used to encapsulate IP packets from the
user's PC or mobile device to the ISP, and L2TP extends that session across the Internet.
Example: Configuring L2TP LAN-to-LAN VPN Connection
The branch office establishes a L2TP VPN tunnel with head office to connect two private networks over the Internet.
The routers are installed in the head office and branch office accordingly.
