VLANs segment a switched network to provide improved performance, manageability, and security. Trunks are used to carry information from multiple VLANs between devices. However, because these VLANs have segmented the network, a Layer 3 process is required to allow traffic to move from one network segment to another. In this chapter, we look at the implementation of inter-VLAN routing.
