LISP

This section provides a focused overview of the Location/Identifier Separation Protocol, commonly known as LISP. It covers the configuration, verification, and troubleshooting processes needed to understand how LISP operates in modern network environments. Throughout this section, learners will explore how LISP separates a device’s identity from its network location, helping improve scalability, mobility, and routing efficiency. The training explains the key LISP components, how they interact, and how traffic is forwarded using the LISP control plane and data plane. The section also covers practical configuration steps, methods to verify correct LISP operation, and troubleshooting techniques for common issues such as mapping problems, reachability failures, encapsulation behavior, and control-plane communication errors. By the end of this section, learners will have a clearer understanding of how LISP works, how it is deployed, and how to validate and troubleshoot LISP-based network designs in real-world environments.
