Start with a Phased Plan Aligned with Your Business Strategy1 Identify the highest priority IPv6-critical areas in your network2 Perform IPv6 Assessment on high priority areas to determine scope3 Develop a design that enables IPv6 without disrupting your IPv4 network4 Test and implement in pilot mode, then extend over time into production Repeat for the Next IPv6-Critical Area in Your Network© 2011 Cisco and/or its affiliates.

  6. 6. Situation Summary Over 2,900 companies have pledged support to turn on and leave IPv6 protocols operating within their networks on June 6th. The web pages accessible from an IPv6 client represents now more than 30% of the internet content. Some of Ciscos biggest customers are participating and have been working with Advanced Services to develop their implementation plans, but many others will have recently upgraded software to enable their IPv6 deployment plans, potentially exposing themselves to previously undetected defects in those code branches. The joint IT and support command center reported no business impacting issues for Cisco internal and customer IPv6 infrastructure in the first 24 hours, and will continue to monitor network and device statistics for the remainder of the week.AssignmentsPrimary Business Function(s): Channels, SalesExecutive Sponsor(s): Padmasree Warrior, Pankaj PatelCurrent StatusAfter the first 24 hours - we have no issues to report from the Cisco internal or customer networks participating in World IPv6 launch.A core team had gathered in San Jose and remotely to provide around the clock monitoring of TAC cases, IT device statistics and problem queues, externalsecurity feeds and source direct customer feedback from our executive sponsored accounts.All indicators of possible problems have been zero. Within TAC, we saw just a handful of IPv6 cases, none of which were network impacting. The securityspace has also been quiet; although ongoing vigilance will be maintained in the event hackers try to attack recently activated IPv6 networks in the comingweeks.The IT support center and change processes executed flawlessly bringing cisco.com to the IPv6 domain.As of today, more than 30% of the Internet content is now reachable from a v6 client and key Internet exchange statistics suggest originating IPv6 traffic hasmore than doubled from earlier in the week.I think it is fair to draw the conclusion from today that our first group of customer deployments were well thought out and implemented. None reported anynetwork impacting situations within their environments under current load conditions. We will want to take this experience and apply it to the next group ofCisco customers who have indicated they will be wanting to add IPv6 capabilities to their networks later in the year.In many cases, Adv Services is already providing consulting to this pipeline of accounts, and so as the numbers increase there is a tremendous opportunityto add services and program guidance to replicate what has worked well.Next Step(s) Continue to monitor IPv6 case indicators and establish regular reporting at the conclusion of the week. Enter the learning phase of the engagement to ensure lessons are identified, captured and shared across participating organisations. Provide input to shape the medium term program responses for customers who are wanting to activate IPv6 later this year based on the foundations established for the worldwide launch.Customer SentimentOverall ownership of Ciscos approach to the World IPv6 Launch is being led by a program called the High Impact Project (HIP). Sponsors for this project areSenior Vice President (SVP), Chief Technology Officer, Padmasree Warrior and SVP, General Manager, Pankaj Patel.© 2011 Cisco and/or its affiliates. All rights reserved.
