Network professionals use IP multicast to establish a smart, one-to-many communication infrastructure that will optimize a network’s bandwidth usage. As IP multicast is used in just about any sector — including finance, enterprise, media, and education — learning how to set it up can be a big plus on your resume. This short course helps build your multicast knowledge so that you can correctly answer most questions about it in either the CCIE or the CCNP certification exams. Specifically, you’ll have a minilab involving a small network made up of six routers where you’ll learn how to prevent RPF (reverse path forwarding) failures and other issues. You’ll also learn how to dynamically advertise RP assignments using different methods.
