IPsec Static and Dynamic VTI

Introduction

In this lesson, we will configure IPsec using Virtual Tunnel Interfaces (VTI), both static and dynamic. This method simplifies the VPN configuration process by allowing us to encapsulate traffic securely without the overhead of traditional methods like GRE.

Quick Recap

In our previous lessons, we set up a basic network topology. For this lesson, we will focus on two routers, R1 and R2, with the following IP addresses:

• R1:
  • Interface F0/0: 10.1.12.1/24
  • Loopback: 1.1.1.1/32
• R2:
  • Interface G0/0: 10.1.12.2/24
  • Loopback: 2.2.2.2/32
