Cisco Intelligent WAN Essentials (IWAN-ESS)

Understand the operation, configuration, and verification of multiple technologies associated with Cisco IWAN solutions.

GK# 5929

Course Overview


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).
