IPv6 routing has many similarities with IPv4 routing; however, the length of the IPv6 addresses can sometimes get in the way of learning the main concepts. This next lab removes those barriers [...]

Ever get tired of sifting through the details of seemingly random IPv6 addresses? Well, today’s lab gives you yet another quick config exercise while using very easy-to-remember IPv6 addresses [...]

IPv6 addresses just take a little getting used to. This next lab gives you same reps with configuring Global Unicast addresses, while giving you a few mind-bending exercises to make you think [...]

Do you know how to take an interface MAC address and determine what IPv6 address the interface would use when using EUI-64? Could you then do the reverse: take the IPv6 address, and predict what [...]

OSPF chooses the best route to reach a subnet based on the lowest cost among all possible routes. OSPF calculates the cost as the sum of the OSPF interface costs of all outgoing interfaces in the [...]

OSPF uses a router’s Router ID (RID) to identify each router. We see the RID in many OSPF verification commands, so using predictable, known OSPF RID values can help people operate [...]

The OSPF network type setting happens to be one of the more useful optional OSPF features. This setting changes a couple of details about how OSPF operates on an interface. Ethernet WAN links [...]

OSPF includes many optional features. Depending on the network, particularly the WAN, you may ignore some of those features while possibly using others. The choice to influence which router [...]
