In this post, we will guide you through the Layer 3 Switch Configuration in Cisco Packet Tracer, specifically focusing on implementing inter-VLAN routing using SVIs. Switch Virtual Interface (SVI): SVI is a logical interface on a multilayer switch that provides layer 3 processing for packets to all switch ports associated with that VLAN. A single SVI can be created for a VLAN. Multilayer switches can forward frames based on MAC address information and can also forward IP packets based on IP. This will let us illustrate the concepts of inter-vlan routing, Router on a Stick (RoaS), and Layer 3 Switches (occasionally called MultiLayer Switches). Why do we need Routing Between VLANs? As we learned in a prior article, VLANs create a logical separation between Switch ports. Essentially, each. A VLAN is a broadcast domain that lives inside your switch. " The. The latest Cisco Catalyst Switches are equipped with the Enhanced Multilayer Image (EMI), which can work as a Layer 3 device with full routing capabilities, also known as a multi-layer switch (MLS). Below are some of the Cisco Catalyst Series switches with Layer 3 functionalities: A Layer 3 Switch. In this sample chapter from Switching, Routing, and Wireless Essentials Companion Guide (CCNAv7) for Cisco Networking Academy students, you will learn how to troubleshoot common inter-VLAN configuration issues.
