  1. IPv6 Road map for IPv6 Migration in an Organization

  2. Agenda • IPv4 to IPv6 Migration Module • Migration Plan • Migration approach • Migration Options • Pilot Implementation • IPv6 Test bed for large organization • IPv6 Training • IPv6 Compliance and Certification • IPv6 Auditing • Case Study

  3. Migration Plan • Study the network and gather information on network infrastructure, key network equipment, servers, appliances and computers, • Gather information on critical applications, • Prepare plan to migrate to a dual stack IPv4/IPv6 network with minimal impact on existing critical applications, and • Prepare a set of strategies covering IT equipment acquisition, new critical applications, manpower resource planning and network policies to prepare for IPv6 compliance audits based on Global Standards

  4. Migration approach • Inventory of current IPv4 addresses and time to address exhaustion. • Identification of IPv4 assets including routers, applications, servers and hosts. • Complexity of existing IPv4 networks

  5. IPv4IPv6 IPv4 IPv6 Network IPv6 Network IPv6 Network IPv4 Network Translator Tunnel Migration Options APPLICATION TCP/UDP • Host/Router - IPv4/IPv6 Dual Stack • Networks - Tunneling • Gateway - IPv4/IPv6 Translation DRIVER IPv4 IPv6

  6. Pilot Implementation • Approach for Large Organization • High cost of Migration • Up-gradation of hardware and software • High cost of application software migration • Approach for Small to Medium Sized Organization • Medium or low cost of Migration • Cost can be reduced if hardware, software up-gradation is done thru regular upgrade cycle

  7. IPv6 Test bed for large organization • Creates scaled version of the network in an isolated and controlled environment. • Test bed must have • Flexibility • Isolation • Partnership • Interoperability • Network

  8. IPv6 Training • Benefits of IPv6 especially to the organization concerned. • Technical specifications of IPv6. • Transition mechanisms available as well as their pros and cons. • Routing schemes and algorithms and how do they differ from IPv4. • Security benefits i.e. IPSec; its uses, benefits and how to set it up. • Security considerations having both IPv4 and IPv6 on the network. • Understanding risks that may have cropped into the upper layer protocols due to bugs introduced in them during the porting.

  9. Course modules on IPv6

  10. IPv6 Compliance and Certification • New procurement of ICT equipment must be IPv6 Ready • Compliance test of products on conformance to the standards set by the IPv6 Forum. • Organization and Solution providers may work jointly sharing the responsibilities

  11. IPv6 Compliance and Certification

  12. IPv6 Audit • Objective • The audit’s objective is to produce an unbiased validation of the IPv6 self compliant status based of the nine suggested RFCs. • To provide consultation on the deployment of IPv6 networks for future setup.

  13. IPv6 Audit • Decision to be taken • Identify any changes that may be needed to our network infrastructure. • Identify hardware used and their level of support of IPv6. • Review existing network diagram to better plan IPv6 deployment.

  14. Summary • Migration Module • Different methodology for Large, medium and small organization • Training • Joint working of service providers and organization

  27. Migration Roadmap • Check IPv6 compliance: • Study the existing network • Recommend upgrade of the equipment • Software upgrade or hardware upgrade/replacement. • All future equipment purchase must ensure that the equipment is IPv6 ready • Plan IPv6 addressing: • Take IPv6 addresses from APNIC or ISP. Make IPv6 Address allocation policy and plan IPv6 addressing for the entire network. • Enable IPv6 routing: • Configure all Layer 3 switches and routers • Enable static/dynamic routing inside the network.

  28. Migration Roadmap • Setup IPv6 Application Servers: • Upgrade the Domain Name servers • Upgrade web servers, mail servers, network management servers • Enable IPv6 peering: • Enable BGP (Border Gateway Protocol) routing for IPv6 peering with ISP to provide Internet access over IPv6. • Migrate Services on IPv6: • Test services like Internet access, Email, VoIP, IPTv etc. on IPv6 and migrate the services to support both IPv6 and IPv4.
