Overview

Description

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. The 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.

 

Note: Students registering for this course will be receiving their course kit in a digital format. To be able to view your digital kit you will need to bring a laptop PC and/or a compatible iPad or Android tablet, the recommended system requirements and instructions to access the course kit content can be found at the following link: Digital Course Kit Requirements and Instructions

Objectives

After completing this course the student should be able to:

  • 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

Prerequisites

The knowledge and skills that a learner must have before attending this course are as follows:

  • Operate LANs with multiple switches, configure VLANs, trunking, spanning tree, DHCP, and port aggregation within Campus network
  • Configure and troubleshoot IPv4 and IPv6 routing within a Enterprise network (static, EIGRP, multi-area OSPF, and RIPng)
  • Implement enterprise Internet connectivity (static routes and basic BGP)
  • Implement route redistribution using filtering mechanisms
  • Implement path control using policy based routing and IP SLA
  • Implement First Hop redundancy in IPv4 and IPv6 environments
  • Configure devices for SNMP, Syslog, and NetFlow access

Who Should Attend

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).
