  1. Nice write-up. I think what would be cool is a follow-up blog entry on why the 6to4 automatic tunnels should NOT be used today in anything other than the lab networks. The 6to4 mechanism itself is pretty cool but it can create the problems if used for one's real-world live traffic. Managed tunnels, if one has to use tunnels, are a much better approach.

  2. Is it possible if we use dynamic routing protocol instead of static route for both of ipv6 segments ?

    Futura(config)#ipv6 route 2001::3/128 2002:C0A8:1703::3   
    Futura(config)#ipv6 route 2002::/16 tunnel 0

    Destiny(config)#ipv6 route 2001::1/128 2002:C0A8:C01::1   
    Destiny(config)#ipv6 route 2002::/16 tunnel 0

    or we just use static route for ipv6 route 2002::/16 tunnel 0 as recursive routing whereas for segment ipv6 2001::YY/128 we use dynamic route.

    Is it possible ? please advice me.

  3. Hey Rene,

    Great write up! Why does Cisco recommend using Automatic 6 to 4 tunneling over ISATAP for inter area routing? I mean, I see the name intra-site, but trying to get more clarity on why ISATAP would not/or could not be used for inter area.

    Thank you


  4. Hi Rene,

    Can you give me an example using BGP instead of static route ??
