Understanding Multicast Routing is a video-based technical course designed to help network engineers build a clear, working understanding of IP multicast in enterprise networks. Taught by Keith Bogart, the course walks learners from foundational multicast concepts—such as multicast addressing, IGMP/MLDP, and distribution trees—into a deep, practical exploration of PIM Sparse Mode, including shared trees, shortest-path trees, Designated Routers, and multicast forwarding behavior. It then covers dynamic Rendezvous Point discovery mechanisms using both Cisco Auto-RP and standards-based PIM BSR, with detailed explanations of elections, message types, and verification techniques. Each video is paired with a multiple-choice review quiz, and hands-on labs reinforce real-world configuration and troubleshooting skills, making the course well-suited for engineers preparing for the Cisco CCNP Enterprise or CCIE Enterprise Infrastructure certifications
