So I'm trying to describe how data is transmitted over a layer 3 switch (within same Vlan and between Vlan) but I'm not sure if I have understood it correctly. Can anybody verify if this description is correct?
A marketing department has computers M1, M2, M3, and the service department has computers S1, S2, S3. If computer M1 wants to communicate with computer M3, the frames from M1 will be sent to the layer 3 switch, within the layer 3 switch it will handle the forwarding as a layer 2 switch, so it will forward the frames to M3 based on M3’s MAC address since they are both on the same Vlan. If computer M1 wants to communicate with computer S2, it will need S2’s IP address, then a packet will be sent over the network, the layer3 switch will handle the forwarding as a layer 3 router and forwards the packet to the S2 computer.
