The Designing for Cisco Internetwork Solutions (DESGN) v3.0 is a 5-day instructor-led course that introduces the learners to the a structured and modular approach to designing networks that are scalable, resilient, and have well-defined failure domains. The content of this course discusses routing and switching design of Campus and Enterprise networks in detail. Data center, wireless networking, and real-time traffic infrastructure are introduced, and their effects on the core network are discussed from the design perspective.
The course enables learners to gather customer internetworking requirements, identify solutions, and design the network infrastructure to ensure basic functionality of the proposed network design.


Upon completing this course, the learner will be able to meet these overall objectives:
  • Describe and apply network design methodologies
  • Describe and apply network design concepts of modularity and hierarchy
  • Design a resilient and scalable Campus network
  • Design a resilient and scalable connectivity between parts of your Enterprise network
  • Design connectivity to the Internet and internal routing for your network
  • Integrate collaboration and wireless infrastructure into your core network
  • Create scalable IPv4 and IPv6 addressing
  • Describe what are software defined networks and describe example solutions
