Understanding Proxy Arp On Cisco Routers – Deep Dive Course

What you'll learn
Clarify some unusual behavior of networks.
Understand Proxy ARP and how it works.
What are Proxy ARP disadvantages.
Security Issues related to Proxy ARP.
Proxy ARP Usage Cases.
Requirements
Student should have basic knowledge of networking especailly with Cisco. Ideally a student should have CCNA knowledge level or Network+ & basic konwledge of Cisco commands.
Description
This course will help you understand some behaviors that seem strange or unusual in networking, such as hosts that do not use a default gateway to communicate with other subnets. You will understand how such things happen.You will understand the mechanisms of an important IP feature, which is the Proxy ARP feature.You will understand the disadvantages and security issues related to this feature, the attacks that it allows, and how to mitigate them.This course focuses on the practical side as much as possible, using Cisco routers emulated in GNS3.For example, we will see how the Proxy ARP feature allows hosts that do not use a default gateway to communicate with other subnets or to use a default gateway that is located outside their own subnet. We will see how this feature affects the cache of the devices, and therefore we will understand what the best way is to configure static routing. Additionally, you will see how both DOS (denial of service) and MiTM (Man in the Middle) attacks take advantage of the Proxy ARP feature. However, this feature was not there without a reason, so its usage cases will be explained.I hope that you will learn—and enjoy—from this course about how proxy ARP works as an example of networking protocols' mechanisms. Happy learning!
