Description

The Cisco Intelligent WAN Essentials (IWAN-ESS) is a 5-day instructor-led course that introduces learners to the theory and deployment of the foundational pillars of Cisco Intelligent WAN (IWAN)—transport independence and intelligent path control. These pillars use technologies such as 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).
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 learners can see first-hand 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).
