Welcome to the IP Multicast: Example-based Study Guide — a complete, hands-on course for network engineers preparing for the CCIE Enterprise Infrastructure exam. This course explains multicast in a way that’s easy to follow and practical to apply. Through examples, diagrams, and labs, you’ll learn how multicast really works across both Layer 2 and Layer 3.
If you’ve ever struggled to fully understand PIM, IGMP, or how multicast flows through your network, this course is for you. Every topic is backed by examples and lab exercises to help you visualize and configure multicast confidently.
About
The IP Multicast: Example-based Study Guide course helps you build deep multicast knowledge from the ground up. You’ll begin with simple local LAN multicast concepts and progress to advanced routing mechanisms used in enterprise and service provider networks.
This course bridges theory and practice with focused labs, packet captures, and troubleshooting exercises. You’ll understand how multicast forwarding works at every layer, how to interpret control-plane messages, and how to diagnose common issues in PIM-based designs.
What you'll learn
- Understand multicast fundamentals: Learn what makes multicast different from unicast and broadcast, and how it saves bandwidth in large networks.
- Master IGMP operations: Explore IGMP messages, membership reports, and how switches use IGMP snooping to control multicast traffic.
- Configure and verify PIM: Work with PIM Dense Mode, learn how neighbors form, and see how multicast trees are built and maintained.
- Design robust multicast networks: Study RPF checks, DR elections, and assert mechanisms to keep multicast forwarding efficient and loop-free.
Skills you'll gain
Who is this for?
Ideal for CCNP and CCIE Enterprise Infrastructure candidates, as well as experienced network engineers who want to understand multicast deeply and apply it in real environments.

Course Structure
The course is divided into three main sections — each focused on a different layer of multicast operation. You’ll start with basic theory and end with full network labs that challenge your understanding and problem-solving skills.
- Section 1: Introduction to IP Multicast — Learn the multicast model, its benefits, and how it differs from unicast and broadcast.
- Section 2: Multicast at Layer 2 — Explore multicast MAC mapping, IGMP, and IGMP Snooping mechanisms on LAN switches.
- Section 3: Multicast at Layer 3 — Deep dive into PIM, RPF checks, Assert process, and advanced routing scenarios.
Each section combines explanations, packet captures, and interactive labs designed to reinforce both conceptual and practical understanding.
By completing the labs and troubleshooting exercises, you’ll be able to configure multicast routing protocols confidently and diagnose real-world issues in Cisco environments.
Outcomes
By the end of this course, you’ll have a clear understanding of how multicast traffic flows through Layer 2 and Layer 3. You’ll know how to configure PIM Dense Mode, verify RPF behavior, and identify IGMP operations in both simulation and production environments.
You’ll also gain the ability to design scalable multicast topologies and troubleshoot issues using real Cisco tools and commands. These skills are not only vital for the CCIE lab exam but also for large-scale enterprise network design.
