ayer 2 technologies form the foundation of enterprise network switching, enabling efficient communication within local area networks (LANs) while ensuring redundancy and loop prevention. This lab covers key Layer 2 concepts such as VLANs, trunking, Spanning Tree Protocol (STP) and its enhancements (RSTP, MSTP), EtherChannel for link aggregation, and switchport security mechanisms.
Advanced topics like VXLAN for Layer 2 extension, Private VLANs for network segmentation, and Loop Guard mechanisms for stability are also explored.
By mastering Layer 2 technologies, network engineers can design high-availability, secure, and scalable switching architectures essential for modern enterprise networks.
