■Recommended Release for Cisco IWAN Release 2.3
■What’s New in Cisco IWAN Release 2.3
This release notes provide a summary of the components in the latest release of the Cisco Intelligent Wide Area Network (Cisco IWAN) Solution.
Cisco IWAN is a prescriptive solution for leveraging multiple transport providers, including low cost business grade broadband services as part of your WAN transport strategy. IWAN is a suite of components that brings all the WAN optimization, performance routing, and security levels of leased lines and expensive MPLS VPN services to the public Internet. IWAN makes it possible to get the performance, reliability and security benefits of private and virtual private network services while allowing the option of using more attractively priced service offerings and require simpler peering relationships with the transport provider. The same prescriptive design may be used with any transport provider; an important flexibility to have when multiple regional providers are needed.
Cisco IWAN can be implemented using Command Line Interface (CLI) commands on the routers of the hub and branch sites.
It is recommended that you use Cisco IOS XE Fuji 16.9.1 for Cisco IWAN.
The new features and enhancements in Cisco IWAN Release 2.3, introduced via Cisco IOS XE Fuji 16.8.1 is as follows:
The Direct Cloud Access (DCA) feature helps customers to optimize their Software as a service (SaaS) applications (Office 365, Google, etc.) with better performance and reduced cost. It continuously measures and monitors the performance of each SaaS application along with local break out path as well as backhaul path, and chooses the best-performing path in policy to provide the most optimal user experience.

Note: From Cisco IOS XE 17.4, PfRv3 is not supported. PfRv3 is integrated with IWAN and support for IWAN is discontinued from Cisco IOS XE 17.3, therefore ending the support for PfRv3.

For more information about how to use the Cisco Bug Search Tool, including how to set email alerts for bugs and to save bugs and searches, you can also see the Help & FAQ within the Bug Search Tool.
This web-based tool provides you with access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in this product and other Cisco hardware and software products. Within the Cisco Bug Search Tool, each bug is given a unique identifier (ID) with a pattern of CSCxxNNNNN, where x is any letter (a-z) and N is any number (0-9). The bug IDs are frequently referenced in Cisco documentation, such as Security Advisories, Field Notices and other Cisco support documents. Technical Assistance Center (TAC) engineers or other Cisco staff can also provide you with the ID for a specific bug. The Cisco Bug Search Tool enables you to filter the bugs so that you only see those in which you are interested.
In addition to being able to search for a specific bug ID, or for all bugs in a product and release, you can filter the open and/or resolved bugs by one or more of the following criteria:
■Status, such as fixed (resolved) or open
