Ediga Ramesh Goud on Instagram: "Today I explained how a Layer 3 switch works and demonstrated it using a Cisco Catalyst 3850. In this video, I covered how to use an L3 switch effectively when no switchport is configured, how routing is enabled on the switch, and how it functions just like a router for inter-VLAN and Layer-3 routing. If you are learning CCNA or working in real-time networks, understanding L3 switching on Cisco platforms is very important. This video will help you understand: • W
