Intent-Based Networking (IBN) enables you to create networks that capture business intent, automatically activate it across your network, assure that your network has responded properly, proactively detect and contain security threats, and remedy other network issues before users even notice. Intent-based networking makes networks dramatically more valuable, but few organizations have the luxury of building them from the ground up. In this guide, leading IBN expert Pieter-Jans Nefkens presents a unique four-phase approach to preparing and transforming existing network infrastructures, architectures, and organization to gain maximum value from IBN with minimum disruption and cost.Writing for network consultants, network architects, network designers, and senior network engineers, Nefkens outlines the problems IBN is intended to solve, and illuminates its implications: not only for technical infrastructure but also for network architecture, team management, and culture. Drawing on his pioneering IBN experience, Nefkens makes specific recommendations, identifies pitfalls, and show how to overcome them. You'll discover how to implement IBN with Cisco's Digital Network Architecture and DNA Center, and walk through several real-world use cases: large enterprise networks, worldwide campus networks, mid-sized enterprises, and smaller businesses.

Network Programmability and Automation, Volume 1, covers designing, implementing, monitoring and operating networks using programmable interfaces on network devices versus the legacy (and soon-to-be obsolete) methods and protocols such as the Command Line Interface (CLI) and Simple Network Management Protocol (SNMP). It discusses the protocols, tools, techniques and technologies upon which Network Programmability is based.Covering the fundamentals that a network engineer needs to transition to the software and programmability domains, the book opens with an introduction that lays the foundation by discussing the market trends and emerging technologies such as SDN, NFV and Cloud, and how network programmability skills are paramount for aligning oneself with these technologies. It provides network engineers with a solid foundation in Python programming and Linux in the context of network programmability and automation.

IP multicast is central to today's enterprise and service provider networks. However, the set of technologies and practices surrounding IP multicast has evolved and matured: older books on the topic are severely out of date. IP Multicast Architectures offers comprehensive guidance for deploying modern IP multicast systems of all kinds: basic and advanced, enterprise and service provider. Focused on Cisco devices and technologies, IP Multicast Architectures addresses common features, deployment models, and field best practices. Each section offers immersive real-world explanations of multicast theory, and present multiple case studies showcasing best-practice multicast design methodologies. Each case study is carefully crafted to offer pragmatic "first-hand" guidance for building the right network for each environment and set of applications. Coverage includes Layer 2 and Layer 3 multicast; routing, forwarding, domains, inter-domain routing, wireless multicast forwarding, Inter-AS, mVPN, mVRF, cloud mVPN transport, and much more. Throughout, the authors' configurations, designs, features, and parameters reflect all that's been learned since IP multicast first became widespread.

In an era of ubiquitous clouds, virtualisation, mobility, and the Internet of Things, information and resources must be accessible anytime, from anywhere. Connectivity to devices and workloads must be seamless even when people move: location must be fully independent of device identity. The LISP protocol makes all this possible. LISP is address-family agnostic, so it can encapsulate any protocol within another, and route across virtually any network. LISP applications include very-large-scale virtualisation for WANs and multi-tenant data centers; host mobility and location services across data centres; advanced mobile networks; ad-hoc networks; IPv6 enablement, seamless site multi-homing; workload mobility; cellular mobility; multicast and traffic engineering, and more. The LISP Network is the first comprehensive, in-depth guide to LISP concepts, architecture, techniques, and applications. Co-authored by LISP co-creator Dino Farinacci and two pioneering developers of Cisco's LISP implementation, this guide will help you plan and implement LISP in any data center, WAN edge, or service provider core network. Largely implementation-agnostic, this book offers actionable answers to questions such as: What problems does LISP address, and how does it address them? How does LISP work? What are LISP's applications, and how do you architect LISP solutions for each application? How does LISP fit with SDN, IoT, and IPv6? What is LISP's future? The LISP Network concludes with detailed deployment case studies of several LISP applications, each drawn from the authors' pioneering experience.

This is today's best single source for the techniques you need to troubleshoot BGP issues in modern Cisco IOS, IOS XR, and NxOS environments. BGP has expanded from being an Internet routing protocol and provides a scalable control plane for a variety of technologies, including MPLS VPNs and VXLAN. Bringing together content previously spread across multiple sources, Troubleshooting BGP describes BGP functions in today's blended service provider and enterprise environments. Two expert authors emphasise the BGP-related issues you're most likely to encounter in real-world deployments, including problems that have caused massive network outages. They fully address convergence and scalability, as well as common concerns such as BGP slow peer, RT constraint filtering, and missing BGP routes. For each issue, key concepts are presented, along with basic configuration, detailed troubleshooting methods, and clear illustrations. Wherever appropriate, OS-specific behaviors are described and analysed.

This is the only comprehensive guide and deployment reference for building flexible data centre network fabrics with VXLAN and BGP EVPN technologies. Writing for experienced network professionals, three leading Cisco experts address everything from standards and protocols to functions, configurations, and operations. The authors first explain why and how data centre fabrics are evolving, and introduce Cisco's fabric journey. Next, they review key switch roles, essential data centre network fabric terminology, and core concepts such as network attributes, control plane details, and the associated data plane encapsulation. Building on this foundation, they provide a deep dive into fabric semantics, efficient creation and addressing of the underlay, multi-tenancy, control and data plane interaction, forwarding flows, external interconnectivity, and service appliance deployments. You'll find detailed tutorials, descriptions, and packet flows that can easily be adapted to accommodate customised deployments. This guide concludes with a full section on fabric management, introducing multiple opportunities to simplify, automate, and orchestrate data centre network fabrics.
