Briefly describe the L2TP protocol.

What will be an ideal response?

Layer 2 Tunneling Protocol (L2TP) is based on two older PPP tunneling protocols, Cisco's Layer 2 Forwarding (L2F) and PPTP, and it uses UDP port 1701. Using L2TP, a host machine can connect to a modem and have its PPP data packets forwarded to another remote access server. L2TP encapsulates the PPP packets. When the data reaches the remote access server, the payload is unpacked and forwarded to the destination host on the internal network.
