which means that the Layer 3 switch is based on the Layer 2 switch. The routing function is added to the above, and the IP addresses of different VLANs can be configured, and the communication between VLANs can be realized through three-layer routing. ...
Compare Layer 2 and Layer 3 network switches and learn when to use each one to create a properly functioning network
1. Layer 3 Switch: A VLAN is designed to segment broadcast domains at layer 2, meaning a switch will only allow traffic within the same VLAN (it won't pass traffic from one VLAN to another VLAN). However, there are options available to route traffic from one VLAN to another VLAN. A ...
This is not a simple Layer 2 switch and router superimposed. Layer 3 routing modules are directly superimposed on the high-speed backplane bus of Layer 2 switching, breaking through the interface rate limit of traditional routers, and the rate can reach tens of Gbit/s. Together with backplane...

As a result, devices in separate VLANs require a Layer 3 forwarding device (e.g.: a router) to communicate with each other. The L3 device can be external to the switch or it can be a feature in the same switch. Layer2-only switches require an external L3 routing device to provide ...
