What Are Vlans? What is an SVI? Network Vlans explained
VLANs are listed as one of the more challenging topics within the CCNP switch series, so I wanted to shed some light on explaining their purpose within networking. I covered Layer 2 and Layer 3 (SVI) vlan differences, and what their purposes are. Furthermore, topology examples of where you would find these vlans configured, why, and how they communicate.
