Enhanced Interior Gateway Routing Protocol (EIGRP) is a powerful distance-vector protocol with advanced features that combine the best of link-state and distance-vector routing. It offers rapid convergence, unequal-cost load balancing, and scalability for enterprise networks. This lab explores EIGRP’s core functionalities, including route summarization, stub routing for network optimization, bandwidth control, and advanced troubleshooting techniques.
By mastering EIGRP’s features—such as DUAL (Diffusing Update Algorithm) for fast route recalculation and IPv4/IPv6 support—network engineers can ensure efficient and resilient routing, making EIGRP a top choice for large-scale enterprise deployments.
