    I am glad to be here. I work on enterprise #ipv6, data center, VDI, OpenStack technologies/designs #clus

    I have worked on enterprise #ipv6 for about 10.5 years. I spend most of my time in DC-related design areas these days. #clus

    I have two breakout sessions again this year. Search for BRKRST-2301 "Enterprise IPv6 Deployment". #clus

    So, no takers yet. I will chat briefly about the top issues I am seeing in Internet Edge #ipv6 deployments. #clus

    The most common issue we have in edge deployments is poor connectivity to the Internet via IPv6. Many reasons for this to include: SLA #clus

    Shannon McFarland@eyepv6
    cont... SLA: poor or no SLA in place with ISP guaranteeing adequate latency/BW/availability. Another is: Poor tunnel broker connection #clus

    cont:Tunnel brokers are fine if you have a stable tunnel connection.Finally,bad routing:Not having the same quality BGP peering is bad #clus

    @eyepv6 Do you see enterprise deployments as edge only? or is there much traction with moving IPv6 to the whole enterprise network? #clus
    Tue, Apr 17 2012 09:17:07
  13. eyepv6
    Shannon McFarland@eyepv6
    @jsnyder81 It used to be internal-only.Now it is mostly edge as the starting point but most still plan internal at the same time #clus

    As I mentioned, your sessions at Cisco Live are very popular. Can you tell us what will be discusses? #clus

    @CiscoLive This year I will have some of the same content as before (designs don't change), but MUCH more on Edge and DC performance. #clus

    Shannon McFarland@eyepv6
    Other items we are seeing in edge designs are with infrastructure security. ppl are not understanding the differences in IPv6 & IPv4.. #clus

    Shannon McFarland@eyepv6
    cont.. IPv6 & IPv4 protocol mechanics are different and ppl must understand what that means to security. #clus

    Shannon McFarland@eyepv6
    For instance, protecting the network infrastructure from DoS attacks like Hop-by-Hop (HbH) extension header attacks can hurt some HW #clus

    Could you provide some design guide or best practices to implement #IPv6 #CLUS? #CLUS

    Shannon McFarland@eyepv6
    @lord2y For sure: You can get three design guides on IPv6 at: bit.ly/brvwck They cover edge, campus and branch #clus

    @eyepv6 Can you explain why it is important to move ADC's closer to their content when they do IPv6 translation? #clus

  23. eyepv6
    Shannon McFarland@eyepv6
    @ehorley Hey Ed! We always recommend moving your ADC as close to content as that allows the most IPv6 visibility north of the ADC #clus

  24. eyepv6
    Shannon McFarland@eyepv6
    @ehorley This is critical when doing IPv6-to-IPv4 translation in the ADC. We want IPv6 visibility in our DPI, Firewalls, IPS/IDS #clus

  25. eyepv6
    Shannon McFarland@eyepv6
    @ehorley Most, if not all of those security components sit between the ADC and Internet. Keeping the ADC towards the content is good #clus
