Course Overview

The Cisco Intelligent WAN (IWAN) Essentials course is an instructor-led, lab-based, hands-on course offered by Cisco Learning Services. It covers the theory and deployment of the foundational pillars of IWAN: transport independence and intelligent path control. These pillars use the following technologies: Dynamic Multipoint VPN (DMVPN), IP Security (IPsec) tunnel protection, routing protocol design (Enhanced Interior Gateway Routing Protocol [EIGRP] and internal Border Gateway Protocol [iBGP]), and Performance Routing (PfR).

5 days
Learning Credits: 
  • The course uses a building-block approach to discussing the operation, configuration, and verification of each technology component. This approach is consistent with the IWAN Cisco Validated Design version 2.x. The lectures include explanations of concepts as well as demonstrations, using a fully functioning lab so that you can see firsthand how each technology is set up and verified for IWAN. The lecture demonstrations and the hands-on labs are performed in a dual data center environment with varying branch office topologies (single and multiple WAN routers).
