I created two Config Labs that use different methods for clients to lease or learn their IPv6 addresses. The first used stateful DHCPv6, while in this Config Lab, you choose, configure, and [...]
IPv6 supports several methods for clients to build their IPv6 addresses and learn other related settings, such as stateful DHCPv6, SLAAC with stateless DHCPv6, and SLAAC with RDNSS. These methods [...]
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 [...]

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 [...]
Use this practice drill for #ICND2 or #CCNA IPv6 practice. Short and sweet: look to the earlier post with 10 practice problems, and today’s post for the answers. The goal: to get good, and to go [...]
Looking for short #ICND2 or #CCNA review tasks? This new practice drill can help. The short version: take a 32-digit hex IPv6 address, and find the shortest abbreviation – or do the opposite. The [...]
Short and icky sweet: this post lists answers for the icky EUI-64 drill 1 for #ICND2 and #CCNA. The problems require you to find the IPv6 address a host or router would use, given a prefix, MAC [...]
This post starts a new type of review post for #ICND2 or #CCNA: the icky EUI-64 drill. It’s icky for two reasons: it requires you to think in binary, and it rhymes. The goal: Starting with a MAC [...]
You take a new #CCENT or #CCNA practice exam, and see a few questions about IPv6 addresses. You focused on the basic format – how to abbreviate, how to expand, and what the prefix length means. [...]
This post answers an earlier config VM piece that asked you to confiugre some IPv6 static routes. (Turns out I forgot to post the answer, so… here it is!) Since it has been so long, if you’re [...]
This blog post begins with a router triangle, IPv6 addresses, and working interfaces. All routers can ping their own IPv6 addresses, but the routers only know their own IPv6 connected routes. [...]
This blog post simply lists the answers to the earlier lab exercise from a few days ago. This post makes no sense without the first one, so don’t look until you read the other post. No guile, no [...]
This blog post creates one of what may be many posts in a concept called the Config Museum. Years from now, this concept may really be a museum of configuration exercises and answers. But just [...]
