Scenario: In this Free CCNA Lab we will use Packet Tracer to troubleshoot a simulated network that was designed and configured to support five VLANs and a separate server network. Inter-VLAN routing is provided by an external router in a router-on-a-stick configuration. However, the network is not working as designed and complaints from your users […]

Spanning Tree Protocol (STP) is an algorithm that provides path redundancy while preventing undesirable loops in a network that are created by multiple active paths between switches. Loops occur when there are alternate routes between two or more switches within the network. To establish path redundancy, STP creates a tree that spans all of the […]
Today network engineers are employing more and more multilayer switched networks. These networks have the advantage of high throughput level 2 switching while retaining the level 3 routing functionality. The secret to the high performance of these networks is the hierarchical design model employing 3 layers Core, Distribution, and Access. This coupled with the advent […]
