In our last article we used Packet tracer to build a dual stack network that supported both IPv4 and IPv6, but because not all networks support dual-stack, tunneling is used to transfer IPv6 traffic across an existing IPv4 networks. Many current internet users do not have IPv6 dual-stack support, and thus cannot reach IPv6 sites […]

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 […]
