There are various overall approaches you can take to QoS in your enterprise network. In this course, you'll learn QoS concepts, with a focus on a differentiated services approach, including modern options for this important set of network services. Network management traffic is critical and should not be ignored in design work for the enterprise, so you'll also explore various techniques for working with network management traffic. Next, you'll learn about designs you can implement for multicast traffic in your routed infrastructure. Finally, you'll examine technologies that assist with multicast design, such as Source-specific Multicast, Bidirectional Protocol Independent Multicast, and Multicast Source Discovery Protocol. This course can be used in preparation for the 300-420: Designing Cisco Enterprise Networks (ENSLD) certification exam.
