Course Schedule


Designing for Cisco Internetwork Solutions (DESGN) 3.0 is an instructor-led course presented by Cisco Systems, Inc., training partners. This five-day course will enable learners to gather customer internetworking requirements, identify solutions, and design the network infrastructure and elements to ensure the basic functionality of the proposed solutions. The purpose of this course is to provide learners with the knowledge and skills to achieve associate-level competency in network design. The DESGN course is the first course in a design curriculum that supports the design certification track. The course focuses on the technology and methods currently available.


After completing this course, students will be able to…

  • Discuss methodology in network design
  • Describe how to structure and modularize the network design using the Cisco Network Architectures for the Enterprise
  • Design the enterprise campus, and describe the architectural approach to the data center and virtualization market
  • Design the enterprise edge and remote modules as needed
  • Design a network addressing plan and select suitable routing protocols for a given network design
  • Evaluate security solutions for the network
  • Discuss voice and video networking considerations in the enterprise network design
  • Recommend a design for a basic wireless solution


  • ndividuals seeking the Cisco CCDA Certification
  • Individuals seeking the Cisco CCDP Certification
  • Presales and postsales network engineers who are involved in enterprise network design, planning, and implementation. (Postsales network engineers who are involved in the implementation will be involved in providing feedback to the presales network engineers and correct possible design flaws.)


To fully benefit from this course, students should have the following prerequisite skills and knowledge:

  • Cisco CCNA level of knowledge and Implementing Cisco IP Switched Networks (SWITCH) level of knowledge are strongly recommended for students attending the DESGN course.
