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 […]
In this Free CCNA Lab you will configure three routers in a simple IPv6 configuration. Multiarea routing will be established using OSPF with three areas one of them a totaly stubby area. Finally you will use the Show and Ping commands verify and test the configuration and connectivity of the network.
In this free CCNA lab, you will troubleshoot an OSPF configuration. The routers and PCs have already been loaded running configuration. These configurations contain errors that will prevent end-to-end communication across the network. You will need to troubleshoot each router to determine the configuration errors, and then use the appropriate commands to correct the configurations. […]
