A VPN tunnel adds privacy and security A VPN tunnel (often simply referred to as a VPN, or virtual private network) is an encrypted connection between your computer or mobile device and the wider internet. Since your connection is encrypted, nobody along the VPN tunnel is able to intercept, monitor, or alter your communications.
VPN protocols are sets of programs and processes that determine how that tunnel is actually formed. Each one is a different solution to the problem of secure, private, and somewhat anonymous internet communication. Layer 2 Tunnel Protocol is the VPN protocol, and it’s usually paired with IPSec for security. L2TP was developed by Cisco and Microsoft in the 90s. What’s it used for? Accessing the internet through a VPN when security and privacy are concerns. PPTP is one of the oldest VPN protocols still knocking about. The first specification for PPTP was published back in the late 90s. This VPN protocol is easy to set up and has almost universal support, but has many caveats you should know about. Plain vanilla PPTP does not actually have a specific authentication or encryption technology specified.

Good question. The answer is because each is programmed, or built differently.
This document describes the process of implementing dynamic routing over a VPN tunnel. Dynamic routing empowers routers to select the paths according to real-time layout changes in logical network.Routing protocol running on the router takes care of the creation, maintenance and updating of the dynamic routing table where as in static
VPN tunnel: What is it and how does it work?
May 24, 2019 · In a VPN, the computers at each end of the tunnel encrypt the data entering the tunnel and decrypt it at the other end. However, a VPN needs more than just a pair of keys to apply encryption. That's where protocols come in. A site-to-site VPN could use either internet protocol security protocol (IPSec) or generic routing encapsulation (GRE).
