May 2, 2023 · As the single broadcast domain is divided into multiple broadcast domains, Routers or layer 3 switches are used for intercommunication between the different VLANs.The process of intercommunication of the different Vlans is known as Inter Vlan Routing (IVR). Suppose we have made 2 logical groups of devices (VLAN) named sales and finance. 05-11-2007 12:11 PM. This would depend upon your requirement. Layer 3 links are preferable as you reduce your broadcast domain size. But if it is a requirement to extend the same vlans across the 2 buildings, then you will have to use L2 links and configure them as trunks. Also you cannot use etherchannel for redundancy across 2 different chassis.The 7 layer salad is a classic dish that has been around for decades.
