It is very important to complete as many practice labs you can find, because if you are like me reading and taking practice test are not enough to prepare you for the real exam. You need to get some real experience configuring, verifying and troubleshooting routing and switching networks. This lab has been designed to […]

In this free CCNA lab we will use Packet Tracer to model several Frame-Relay scenarios to help us understand and configure Frame-Relay. These scenarios will include Full Mesh, Hub and Spoke, and Sub Interfaces. We will also explore the problems that may occur when using a Dynamic Routing protocol such as RIP, EIGRP, or OSPF. […]

In this free CCNA lab we will use Packet Tracer to learn how to configure Open Shortest Path First (OSPF) routing protocol to connect multiple discontigous areas. As you can see from the network diagram we have two OSPF areas that are not directly connected to OSPF backbone area 0. There is also a discontinuity […]

Introduction: Access Control List (ACL) is an important part of the day to day duties of a network engineer. Security being a key part of today’s network design and ACL’s play a very important role in implementing this security. Today’s network engineers and technicians need to have a good understanding of how ACL’s work, how […]
