The longer you wait, the higher price you pay IPv4/IPv6 Co-existence IPv6 Government Mandate DeadlinesRisk from inaction Globalization 2014: IPv6 is mainstream Providers without transition Early infrastructure will experience reduced Adopters service levels and customer reach Transition Planning 2012: Mandates take effect Globalization and massive mobile 2010: Low Impact deployments force IPv6 transitions Shift if buying behavior limited to mandated and early adopters 2010 2012 2014 © 2011 Cisco and/or its affiliates.

  • 8. • IPv6 is designed as a direct replacement for IPv4 Provides familiar best-effort datagram delivery IPv6 address has a prefix to identify the destination subnet and a suffix to identify the host interface Not backward compatible with IPv4; carried in parallel as a multi-protocol network• 128-bit addresses solve address exhaustion problem Prefix/suffix boundary effectively fixed at 64 bits Fixed prefix makes address architecture a prefix assignment problem rather than a subnet size problem 64 bit identifier allows hosts to self-assign addresses, in addition to DHCP• Home networks will use global IPv6 addresses Restores full connectivity to devices in the home Utilizes extensions to DHCPv6 for prefix assignment automation© 2011 Cisco and/or its affiliates.

  • 9. Dual Stack Tunneling Translation (NAT) • Typically easiest to • Encapsulate v6 traffic • Allows multiple local implement in v4 packets (and addresses to share vice versa) single IP address • Built into many modern operating • Can reduce efficiency • Not true end-to-end systems connectivity • Routing can be • Implements v4 and v6 sub-optimal • Can create independently, as well complications and as in hybrid form disruptions “Dual stack when …tunnel where you …translate when you you can… need to… must.”© 2011 Cisco and/or its affiliates.

  • 22. Proactively budget your time, money, and resources Prioritize Critical Areas of Your Business and Network as You Scale Beyond IPv4 Solution Overview Through a Phased Approach, We Help You: IPv6 adoption must be 1. Identify the highest priority IPv6-critical areas in your addressed using a phased network. approach with careful validation 2. Assess those areas to determine the scope of your IPv6 and testing to avoid disrupting design. the IPv4 network or introducing vulnerabilities. 3. Develop a design that enables IPv6 to be introduced without disrupting your IPv4 network. 4. Test and implement IPv6 in pilot mode, then extend over time into production deployment. 5. Repeat steps for subsequent areas of your network through ongoing optimization.© 2011 Cisco and/or its affiliates. All rights reserved.
