EIGRP Authentication (MD5 and SHA)

EIGRP Authentication (MD5 and SHA)

Introduction

In this lesson, we will configure MD5 authentication between EIGRP neighbors to ensure that routing updates are secure and only trusted routers can exchange routing information. This is crucial in real networks to prevent unauthorized access and routing attacks.

Quick Recap

In the previous lessons, we configured EIGRP on routers R1, R2, R3, R4, R6, and R7. The topology remains the same, and we will now focus on adding authentication to the EIGRP configurations.
