About this learning path

The Cisco Layer 2 Fundamentals Learning Path focuses on key networking concepts including VLANs, Trunks, CDP, LLDP, and UDLD. It starts with understanding how VLANs segment networks for better security and performance, followed by learning how trunk links enable communication between VLANs. You'll explore CDP and LLDP to discover network devices and topologies, and finally dive into UDLD for preventing unidirectional link failures. This path equips you with essential skills to manage, secure, and troubleshoot Layer 2 networks, providing a strong foundation for more advanced networking topics.
