ou have been appointed as the network administrator of an ISP. Your first project requires you to develop a protocol that can transmit IP and other kinds of messages through a tunnel so that you can connect two VPN endpoints.

Question

Which of the following will you choose in this scenario?

Answer 1

In this scenario, I would choose to develop a VPN protocol that supports encapsulation of IP and other kinds of messages through a tunnel. One common protocol that can be used for this purpose is the Layer 2 Tunneling Protocol (L2TP) which enables the creation of virtual private networks over the internet. L2TP encapsulates data in PPP frames and then tunnels them through IP networks, providing a secure means of communication between two VPN endpoints.
