  Designing for Cisco Internetwork Solutions v1.2

Course Description

The Designing for Cisco Internetwork Solutions (DESGN) Course version 1.1 is almost identical with version 1.0 in addition to general approaches and technologies for network design, it 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 formalize. 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 optimizing/troubleshooting (PDIOO) 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.

Course Objectives

Upon completion of the Designing for Cisco Internetwork Solutions (DESGN) course the student will be able to:

  • Assess the customer requirements and the customer?s existing situation
  • Design a network addressing plan
  • Select optimal routing protocols for the network
  • Recognize network management criteria for the network
  • Recognize security criteria for the network
  • Design the Enterprise network in a hierarchical modular fashion
  • Assess the design implications of voice transport across the network
  • Plan the design implementation
  • Explain the network design and its impact to the customer

Course Summary and Overview


The prerequisite for the students attending the Designing for Cisco Internetwork Solutions (DESGN) course is the Cisco Certified Network Associate (CCNA) certification or equivalent level of working knowledge and experience. This can be best achieved by taking the Intro to Cisco Networking Technologies and Interconnecting Cisco Network Devices (ICND) courses. Practical experience with deploying and operating networks based on Cisco network devices and Cisco IOS is strongly recommended.

The students 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.
