Config Lab: IPv6 Special Addresses 1
This latest config lab takes a backwards approach to configuration. In this case, it starts with a bunch of show commands, and asks you to derive some of the key configuration items on several routers. The theme: IPv6 addressing. By
Config Lab: IPv6 Static Routes 3
Although this lab’s title is “IPv6 Static Routes 3”, it might be better called “Convoluted Fun with overlapping IPv6 Static Routes using Administrative Distance”. The purpose of the lab is to exercise a couple of specific ideas: how a router
Config Lab: IPv6 Static Routes 2
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 with a straightforward IPv6 static route configuration lab.
Config Lab: IPv6 Static Routes 1
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 and prefixes. The task today: configuring static IPv6 routes. All the
Config Lab: IPv6 Global Unicast Addressing 1
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 about Link Local addresses and EUI-64. I would
Config Lab: IPv6 EUI-64 Addressing 1
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 MAC address is used for
Config Lab: OSPF Metrics
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 route. Unsurprisingly, you can
Config Lab: OSPF Router IDs
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 networks. This lab asks you to configure the OSPF
