Course CI-DESGN—Five days—Instructor-led

Who Needs to Attend

Channel Partner/Reseller


The prerequisites for delegates attending the Designing for Cisco Internetwork Solutions (DESGN) course are the Introduction to Cisco Networking Technologies (INTRO) and the Interconnecting Cisco Network Devices (ICND) courses, which are required for the Cisco Certified Network Associate (CCNA) certification, or the equivalent working knowledge and experience.

The delegates with Cisco Certified Network Professional (CCNP) or equivalent level of knowledge and experience will probably have the advantage of being able to participate more actively in classroom discussions.

Introduction to Cisco Networking Technologies (INTRO)
Interconnecting Cisco Network Devices (ICND)

Course Objectives

After attending this course, the delegate will be able to:

Describe the principles of network design for building a network design solution
Describe how the Enterprise Composite Network Model simplifies the complexity of modern networks
Design the enterprise campus in a hierarchical modular fashion
Design the enterprise WAN network
Design a network addressing plan
Select optimal routing protocols for the network
Evaluate security solutions for the network
Assess the design implications of voice transport across the network
Recognise the network management criteria for the network

 Course Outline

The Designing for Cisco Internetwork Solutions (DESGN) Course promotes Cisco solutions in designing and implementing scalable internetworks. Among specific goals is the promotion of the new modular approach to network design that has been intuitively used for the last few years and that Cisco now wants to formalise. The early modular approaches to network design divided networks into access, distribution and core layers only, separately for the campus and the WAN part. The new Enterprise Composite Model facilitates designing, planning, implementing, operating and troubleshooting (PDIOT) networks by concentration on a certain module and on relations between the modules. Taking into account that most network solutions today (e.g. voice, video, storage networking, content networking) are typically overlay solutions spanning several modules, the composite modular approach seems even more relevant and is the main focus of this course
