After waking up from cryosleep the year appears to be 2020 and there is not a single IPv4 address left on the planet. The last thing you remember are the stories about the end of IPv4 and the migration plans for IPv6…now it seems this is all reality! It’s up to you to configure EIGRP for IPv6 and make the network operational…resistance is futile đŸ˜‰


  • You are not allowed to use IPv4 addresses.
  • You are not allowed to use any IPv6 global unicast addresses except the ones on the loopback interfaces.
  • Use the MAC-address for the last 64 bits of the IPv6 addresses required for the FastEthernet links.
  • Configure EIGRP AS 6 and achieve full connectivity between the networks on the loopback interfaces.
  • Configure the FastEthernet 0/0 interface of router Romulan so EIGRP can use up to 75% of available bandwidth.
  • Configure EIGRP authentication between router Borg and Klingon. Use password GNS3VAULT.
  • Change the EIGRP hello interval to 9 seconds between router Vulcan and Borg.

It took me 1000s of hours reading books and doing labs, making mistakes over and over again until I mastered all the routing protocols for CCNP.

Would you like to be a master of routing too? In a short time without having to read 900 page books or google the answers to your questions and browsing through forums?

I collected all my knowledge and created a single book for you that has everything you need to know to become a master of routing.

You will learn all the secrets about IPv6, routing protocols and more.

Does this sound interesting to you? Take a look here and let me show you how to Master CCNP ROUTE

  1. Not a question, just an observation that might help someone else if they feel something is wrong when trying to do this lab (which there is not).

    Ran into an interesting scenario when I tried to use a 3640 IOS image in GNS3 for this lab. The ‘ipv6 router’ command only supports OSPF and RIP. For EIGRP we need the specific 3725 image.

    Great lab and I like the addition of authentication and bandwidth. It allows for a more ‘realistic’ scenario. On a different note, in the future it would be awesome to have longer labs (60+ min). Maybe as a ‘paying member’ option.

  2. Good comment Daniel. When I started building labs I used the C3640 image for most of the labs. The 3725 series however covers everything the C3640 has and more. I think if I had to recreate everything I would use that IOS image for all labs.

    I might think about some ‘paid member’ labs. It’s possible to create really advanced topologies for EIGRP, OSPF, BGP, IPv6 and more.

    1. Paid member labs are a great idea. This would create the opportunity to walk through the syllabus more in-depth.

      Specifically in the new ROUTE guide more attention is placed on network engineering soft skills such as Design, Implementation and Verification planning, which will require more time to demonstrate and "mentor" in the labs.

    2. the paid member would be great,

      as long as you can keep it affordable to students,


  3. I cannot seem to get the 3725 ios that i do have to open. keep getting the “ghost” error. I have gotten all other ios’s to open, however. Must be missing something?

    1. I’m not sure which IOS image you have but keep in mind some of them just don’t run well in GNS3. The ones I use are 100% stable so if you keep getting errors I can highly recommend to try another one!

  4. Hi mate

    I cant get this one started at al is there a new .net file for the 3725 image or can I quickly change the current one ?



  5. Rene, I noticed that the lab files contain the OSPF routers with C3600 not C3725. Can you please check?
