It doesn't matter if you are completely new to Cisco ACI or you already have some experience with the technology, this book will guide you through the whole implementation lifecycle and provide you with a comprehensive toolset to become confident in any ACI-related task. In the beginning, it's very important to build strong fundamental knowledge about Cisco ACI components. We'll go through underlay networking based on Nexus 9000 switches and describe the APIC controller cluster acting as the management plane of ACI. By building Access Policies, you'll see how to optimally connect servers, storage, routers, switches, or L4-L7 service devices to ACI. Then we'll properly design and implement Logical Application Policies. You will understand all the fabric forwarding behavior when using different ACI settings and architectures while getting a toolset on how to verify and troubleshoot eventual problems. This book also covers external L2 and L3 connectivity in ACI, more advanced features like integration with virtualization hypervisors and Kubernetes, service chaining of L4-L7 devices using Service Graphs, or practical approach to using REST API automation based on Python and Ansible/Terraform. Cisco ACI: Zero to Hero can additionally be used as a valuable source of theoretical and practical knowledge for all candidates preparing for CCIE DC v3.0 Written or Lab exams. What You'll Learn Understand network evolution and Cisco ACI components Underlay ACI networking based on Nexus 9000 switches, APIC controllers, and Application Policy Model Integrate ACI with virtualization hypervisors and Kubernetes Dynamically and seamlessly include L4-L7 service devices in communication between ACI endpoints Build ACI Anywhere: ACI Multi-Tier, Stretched Fabric, Multi-POD, Multi-Site, and Remote Leaf Utilize ACI REST API with Python, related Cobra SDK, Ansible or Terraform, to develop automation and scripts on top of the ACI platform Who This Book Is For Network engineers, architects, network developers, administrators or NOC technicians.

This work provides a guide to the configuration of Cisco routers, from tasks for beginners to advanced operations. A collection of detailed "how-to" instructions are presented, which will be of use to all professionals and students who engage with Cisco routers in the field or in the lab. The guide starts with the simple step-by-step task of connecting the router and performing basic configuration, before building up to complex and sensitive operations such as router IOS upgrade and Site-to-Site VPNs.
