This intermediate learning path on Open Shortest Path First (OSPF) is tailored for network professionals who are ready to move beyond the basics and develop a deeper, more practical understanding of OSPF in enterprise networks. The path explores key deployment and optimization techniques including route redistribution between OSPF and other protocols, effective route summarization at ABRs and ASBRs, and implementing route filtering to control routing information flow. It also covers OSPF area types in detail, including standard stub areas, totally stubby areas, and Not-So-Stubby Areas (NSSA), with guidance on when and how to use each to simplify routing and improve scalability. Throughout, the learning path emphasizes best practices, common design mistakes to avoid, and hands-on configuration strategies to help learners confidently apply OSPF in complex, real-world environments.

This learning path provides a comprehensive introduction to Cisco Catalyst Center, guiding network professionals through the platform's core features and advanced capabilities. Learners will start by understanding the hierarchical design model and how it supports scalable management and policy deployment. The course covers device discovery, inventory management, and provisioning workflows, enabling consistent network configuration and automation. It also addresses software image upgrades, lifecycle management, including End-of-Life (EoX) insights, and essential system administration tasks. A significant portion is dedicated to Software-Defined Access (SDA) fabric design, including control and border nodes, as well as implementing secure, policy-driven segmentation through micro-segmentation using Security Group Tags (SGTs). By the end, participants will be equipped to deploy, operate, and optimize Cisco Catalyst Center in modern enterprise environments.

This Learning Path will take you through configuration of Aruba 8360 and 6300F AOS-CX switches from OSPF to VSX. Aruba CX switches run on the AOS-CX, which is built to provide advanced networking capabilities. When configuring a WLAN in Aruba Central, you can choose different forwarding modes based on network requirements such as Bridged Mode and Tunneled Mode. WLANs are configured and managed through the cloud-based interface of Aruba Central. Aruba Central is Aruba's cloud-based network management platform.
