Learning SD-WAN with Cisco by Stuart Fordham Pdf

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

Cisco Cookbook by Kevin Dooley,Ian Brown Pdf

While several publishers (including O'Reilly) supply excellent documentation of router features, the trick is knowing when, why, and how to use these features There are often many different ways to solve any given networking problem using Cisco devices, and some solutions are clearly more effective than others. The pressing question for a network engineer is which of the many potential solutions is the most appropriate for a particular situation. Once you have decided to use a particular feature, how should you implement it? Unfortunately, the documentation describing a particular command or feature frequently does very little to answer either of these questions.Everybody who has worked with Cisco routers for any length of time has had to ask their friends and co-workers for example router configuration files that show how to solve a common problem. A good working configuration example can often save huge amounts of time and frustration when implementing a feature that you've never used before. The Cisco Cookbook gathers hundreds of example router configurations all in one place.As the name suggests, Cisco Cookbook is organized as a series of recipes. Each recipe begins with a problem statement that describes a common situation that you might face. After each problem statement is a brief solution that shows a sample router configuration or script that you can use to resolve this particular problem. A discussion section then describes the solution, how it works, and when you should or should not use it. The chapters are organized by the feature or protocol discussed. If you are looking for information on a particular feature such as NAT, NTP or SNMP, you can turn to that chapter and find a variety of related recipes. Most chapters list basic problems first, and any unusual or complicated situations last.The Cisco Cookbook will quickly become your "go to" resource for researching and solving complex router configuration issues, saving you time and making your network more efficient. It covers: Router Configuration and File Management Router Management User Access and Privilege Levels TACACS+ IP Routing RIP EIGRP OSPF BGP Frame Relay Queueing and Congestion Tunnels and VPNs Dial Backup NTP and Time DLSw Router Interfaces and Media Simple Network Management Protocol Logging Access Lists DHCP NAT Hot Standby Router Protocol IP Multicast
