Migrate to Intent-Based Networking–and improve network manageability, cost, agility, security, and simplicity With Intent-Based Networking (IBN), you can create networks that capture and automatically activate business intent, assure that your network responds properly, proactively detect and contain security threats, and remedy network issues before users even notice. Intent-Based Networking makes networks far more valuable, but few organizations have the luxury of building them from the ground up. In this book, leading expert Pieter-Jans Nefkens presents a unique four-phase approach to preparing and transforming campus network infrastructures, architectures, and organization–helping you gain maximum value from IBN with minimum disruption and cost. The author reviews the problems IBN is intended to solve, and illuminates its technical, business, and cultural implications. Drawing on his pioneering experience, he makes specific recommendations, identifies pitfalls, and shows how to overcome them. You’ll learn how to implement IBN with the Cisco Digital Network Architecture and DNA Center and walk through real-world use cases. In a practical appendix, Nefkens even offers detailed technical configurations to jumpstart your own transformation. Review classic campus network deployments and understand why they need to change Learn how Cisco Digital Network Architecture (DNA) provides a solid foundation for state-of-the-art next generation network infrastructures Understand “intent” and how it can be applied to network infrastructure Explore tools for enabling, automating, and assuring Intent-Based Networking within campus networks Transform to Intent-Based Networking using a four-phased approach: Identify challenges; Prepare for Intent; Design and Deploy; and Enable Intent Anticipate how Intent-Based Networking will change your enterprise architecture, IT operations, and business

Explore the rise of SD-WAN with CISCO and transform your existing WAN into an agile, efficient, and cost-effective network. Learning SD-WAN with Cisco helps you understand the development of SD-WAN and its benefits to modern networks. This book starts with an exploration of the different components of SD-WAN, such as vBond for orchestration, vManage for management, vSmart for control, and the vEdge devices. From there, it moves on to building a network from the ground up using EVE-NG, focusing on how to install EVE-NG, get the required licenses via a SmartNET account, download the components, and begin to create your network by installing vManage. Once you have this foundation, you will create the organization and certificates, and look at local users as well as single- and multi-tenancy options and clustering. As you continue to build your network, you will dig down into the overlay protocols used in SD-WAN, and then deploy your controllers and edge devices, looking at zero-touch provisioning along the way. After building your network, you will configure and apply policies and templates to manage the control and data planes as well as VPNs, Internet access, security, and quality of service. The book also explores reporting and management using vManage, along with upgrading and troubleshooting the various components, using techniques from simple ping and trace route through to advanced techniques such as DTLS and TLOC troubleshooting and traffic simulation. After reading this book, you will have hands-on experience working with SD-WAN. You will understand how to deploy, configure, manage, and troubleshoot it. What You Will Learn Know what SD-WAN is, how it came about, and why we need it Understand troubleshooting and traffic simulation of DTLS and TLOC Monitor, report, and troubleshoot the SD-WAN environment Who This Book Is For Network professionals with experience in Linux and Cisco devices
