  1. Hello RENE,
    Thank you for your nice posts.
    I have some questions about adressing a network in IPv6:
    Is there any rules to address an IPv6 network?
    Can we for example use some small subnets such as /120 or should we always work with /64?
    And if we are using stateful, shoud we use /64?
    Thank you for your help

  2. Hi Imin,

    It’s probably the IOS version. I wrote this tutorial using my 2800 routers running IOS 15.x. I checked it on a 3725 router in GNS3 running 12.4T and it also doesn’t support this command.


  3. I managed to get this lab to work correctly with GNS3 1.5.2 and below IOS´s
