Overview of Cisco Intelligent WAN (IWAN)
Cisco IWAN is a system that enhances collaboration and cloud application performance while reducing the operating cost of the WAN. This system leverages low-cost, high-bandwidth Internet services to increase bandwidth capacity without compromising the performance, availability, or security of cloud-based applications. Organizations can use IWAN to leverage the Internet as WAN transport, as well as for direct access to Public Cloud applications. See Cisco Intelligent WAN (IWAN) Design Guide, for more information.
positions the IWAN wizard workflow mostly for green field customers where the IWAN services need to be enabled for the first time. The enabled IWAN service cannot be modified for brown field customers. But customers can always overwrite the last-configured service by rewriting any of these services on required sites.
You can use to design, configure, and monitor the IWAN services for an enterprise. Cisco IWAN requires the configuration of DMVPN, PFR, AVC and QOS as part of enabling IWAN services on different devices.
