road map for ipv6

IPv6 10/24/14 1 Road map for IPv6 Migration in an Organization 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 2 Migration Plan 10/24/14 3 • 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 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  Host/Router - IPv4/IPv6 Dual Stack  Networks - Tunneling  Gateway - IPv4/IPv6 Translation DRIVER APPLICATION TCP/UDP IPv4 IPv6 IPv4 IPv6 IPv6 Network IPv4 IPv6 Network Tunnel IPv4 Network IPv6 Network Translator Migration Options • Approach for Large Organization 1. High cost of Migration 2. Up-gradation of hardware and software 3. High cost of application software migration • Approach for Small to Medium Sized Organization 1. Medium or low cost of Migration 2. Cost can be reduced if hardware, software up- gradation is done thru regular upgrade cycle Pilot Implementation 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 10/24/14 7 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. 10/24/14 8 IPv6 Advance Courses Client & servers configuration in IPv6 IPv6 Basic Courses IP v6 Awareness Courses Learning IP v6 Course modules on IPv6 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 10/24/14 10 [...]... 12.2(25r)SEE1 IPv6 support available IPv6 support not available 12.3(4r)T3 IPv6 support available 33 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... 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 34 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...
