Cisco Intelligent WAN Essentials (IWAN-ESS)

  • Systems engineers
  • Field engineers
  • Implementation engineers
  • Network operations engineers


  • Network deployment experience equivalent to the Cisco CCNP Routing and Switching certification
  • Fundamental understanding and practical experience configuring EIGRP and iBGP
  • Fundamental understanding and practical experience configuring GRE and IPsec

Expected Duration
5 day


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).
