DESGN 3.0: Designing a Highly Available Campus Network

This path is intended for anyone who is interested in developing the skills needed to successfully design networks that will support voice, video, and data communications.


Expected Duration
90 minutes

Providing high availability within a campus is essential for business success. Every second the network is down is costly. Your goal should be to provide adequate bandwidth, redundant devices, redundant connections, and redundant services, within a Campus and between Campuses. This course describes how you can implement high availability within the Campus using redundant links, port aggregation, VSS, stacking, and first hop redundancy protocols. It also describes what you need to consider when implementing Layer 3 within your design. To wrap up the course, focus is placed on what you need to keep in mind when you are interconnecting devices within a campus and between campuses to support resources.
