GRE Tunnel Basics
Lesson 1 of 7
Introduction
In this lesson, we will configure a basic GRE tunnel between two routers, R1 and R3. This configuration is essential for establishing a point-to-point connection over an IP network, allowing us to encapsulate packets for secure transmission. Understanding GRE tunnels is crucial for building scalable and efficient networks, especially when integrating remote sites.
