Compare the advantages and disadvantages of each type of switch and how to choose the best one for your network. Step 1. Before you configure the Layer 3 switch, create static routes in the gateway router to each of the new subnets. In this example, my gateway router uses a LAN subnet of 192.168.199.0, so I need to create static routes on the router to the 192.168.7. 0 and 192.168.8.0 subnets. Static Routes on a Router.Layer 3 switch is a mix of switch and router, which is commonly used for routing within virtual LANs (VLANs). Speed: Normally, switches operating at layer 2 take less time than that operating at layer 3. Layer 2 switches just need to assign MAC addresses to reroute packets from source port to destination port in …Also the presence of VLAN’s does not denote that the switch is layer 3 as layer 2 switches will often have VLAN’s but they cannot do routing (and it is the routing part that makes a device layer 3).
