  6. 6. IPv6/IPv4 Dual Stack Hosts • Dual Stack = Two protocols running at the same time (IPv4/IPv6) Access • #1 requirement—switching/ routing Layer platforms must support hardware L2/L3 based forwarding for IPv6 Distribution Layer • Expect to run the same IGPs as with v6- Enabled v6- Enabled IPv4 v6- v6- Core Layer Enabled Enabled Aggregation v6-Enabled v6-Enabled Layer (DC) Access Layer (DC) Dual-stack Server© 2010 Cisco and/or its affiliates.

  7. 7. VLAN 2 VLAN 3 IPv4-only Campus • Provides ability to rapidly deploy IPv6 Block services without touching existing network ISATAP Access • Provides tight control of where IPv6 is Layer deployed and where the traffic flows (maintain separation of groups/locations) IPv6 Service Block • Get lots of operational experience with limited impact to existing environment Dist. Layer Dedicated FW 2 – Ideal for Pilot • challenges – Lots of tunneling • 1) Leverage existing ISP block for both Core IPv4 and IPv6 access Layer Internet • 2) Use dedicated ISP connection just for IPv6—Can use FW on router or dedicated appliance Agg FW on router Layer Access Layer Primary ISATAP Tunnel 1 Secondary ISATAP Tunnel WAN/ISP Block Data Center Block© 2010 Cisco and/or its affiliates.

Pre-Deployment Deployment Phases Phases • Establish the network • Transport considerations starting point for integration • Importance of a network • Internet Edge (ISP, Apps) assessment and available tools • Campus IPv6 integration • Build a pilot or lab environment options • Obtain addressing or use ULA • Data Center integration options or documentation prefix (in lab) • WAN IPv6 integration options • Learn the basics (DNS, routing changes, address assignment) • Execute on gaps found in assessment© 2010 Cisco and/or its affiliates.

John Chambers Planning •2012: Mandates take effect – Transition to IPv6 forces customers to acquire product or managed services to sustain business and customer reach • 2014: IPv6 is mainstream – customers without transition infrastructure experience reduced service levels, diminished customer reach, increase operational complexity IPv6 Business Impact – The Cost of Waiting Goes Up Low Risk© 2010 Cisco and/or its affiliates.
