Which of the following protocols can be directly used for point-to-point connections on MikroTik?

PPP, or Point-to-Point Protocol, is specifically designed for direct connections between two network nodes, making it ideal for point-to-point scenarios. It is widely used for dial-up connections, but its versatility allows it to support various types of links, including serial connections, DSL, and more.

When establishing a point-to-point connection, PPP facilitates the establishment, configuration, testing, and termination of these links while providing features such as error detection, authentication, and network layer protocol encapsulation. The ability to maintain a direct and reliable connection makes it the most suitable protocol for point-to-point communications on MikroTik devices.

While other protocols listed play important roles in networking, they do not configure point-to-point connections in the same fundamental way that PPP does. For instance, IPSec is primarily focused on securing communications across IP networks and does not establish the connection itself. L2TP is a tunneling protocol that often relies on PPP for authentication and encapsulation but does not directly connect two endpoints. CHAP, which stands for Challenge Handshake Authentication Protocol, is an authentication protocol that operates within PPP sessions, but it does not establish the connection. Thus, while these other protocols have their own specific functions in networking, PPP is uniquely designed for point-to-point
