Cisco® Designing for Cisco® Internetwork Solutions v3.0 (DESGN)



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.

Audience Profile

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).

Prerequisite(s) Recommended

CCNA certification is highly recommended. Familiarity with basic internetworking technologies such as LAN, WAN, bridging, switching, protocols, and network management.

Learning Objectives

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/li>
  • Configure devices for SNMP, Syslog, and NetFlow access
  • Secure campus network according to recommended practices
