Designing for Cisco Internetwork Solutions (DESGN)

Course Overview

Designing for Cisco Internetwork Solutions (DESGN) v3.0 course presents a structured and modular approach to designing networks that are scalable, resilient, and have well-defined failure domains. 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.

Target Audience

The target audience for the DESGN course consists of individuals seeking the Cisco Certified Design Associate (CCDA) certification and those individuals targeting towards the CCDP (Cisco Certified Design Professional) certification. The course is also targeted at pre-sales and post-sales network engineers involved in the Enterprise network design, planning and implementation. (The post-sales network engineers involved in the implementation will be involved in providing feedback to the pre-sales network engineers and correct possible design flaws).


It is recomended that you have attended either Interconnecting Cisco Networking Devices Part 1 (ICND 1) or Interconnecting Cisco Networking Devices Accelerated (CCNAX) and/or have either a CCENT or CCNA Routing and Switching certification.
