Learn about IP features and how they work on Cisco routers.
What you'll learn
Understand IP features and how they work.
Clarify some unusual behavior in networks.
The Proxy ARP feature.
The ICMP Redirects feature
The IP Smurfing Attack using The IP Directed Broadcasts feature.
Requirements
Students should have basic knowledge of networking especailly with Cisco. Ideally a student should have CCNA knowledge level or Network+ & basic knowledge of Cisco commands.
Description
It is crucial for network engineers to understand how networking protocols work in depth. This will help them to configure and operate networks effectively and be distinguished from other engineers who do not possess this understanding.This type of knowledge is also important for network architects. It will allow them to design networks that consist of parts that work together in harmony.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 some important IP features, such as Proxy ARP, IP redirects, and IP directed Broadcasts.You will understand the disadvantages and security issues related to these features, the attacks that they allow, and how to mitigate them. This course focuses on the practical side as much as possible, using Cisco routers emulated in GNS3. We will deep dive into protocols' behaviors with show and debug commands.For example, we will see how the Proxy ARP feature allows hosts that do not have a default gateway configured 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 will understand what is the best way to configure static routing. Additionally, we will see how both the 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.Another example is how the IP directed Broadcasts feature allows for the IP Smurfing attack to occur and how we can mitigate this attack using the uRPF (unicast Reverse Path Forwarding) mechanism.
