  1. IPv6 Campus TransitionScenario Descriptionand Analysis Tim Chown University of Southampton (UK) tjc@ecs.soton.ac.uk IETF 66, July 12th 2006 Montreal

  2. Purpose of this document • Validate the approach taken in the IPv6 Enterprise Network Scenarios text (now RFC 4057) • Document the approach taken to deploy IPv6 (dual-stack) in a medium-size campus enterprise, and the specific tools used • Feed into IPv6 Enterprise Network Analysis text, on relevance and usage of various tools • Document ‘gaps’ in deployment

  3. RFC 4057 (Ent. Scenarios) • Describes an approach to plan your enterprise IPv6 transition/integration process • We validate that approach in Sections 2, 3 and 4: • University department (1,000+ hosts, 1,500+ users) • Network infrastructure components • Network infrastructure component requirements • Specific scenario component review • We found this covered 95%+ of our needs • (Two) missing considerations listed in Section 9 • e.g. WLAN access control

  4. Analysis • Section 5: dual-stack deployment procedure • We describe three phases: • Advanced planning • Testbed/trial deployment • Production deployment • Section 6: Transition toolbox discussion • We used VLANs (draft-ietf-v6ops-vlan-usage-01) as an interim measure, IPv6 tunnel broker, 6to4 relay • We didn’t use NAT-PT, ISATAP, Teredo

  5. Missing components • Covered in Section 8 • Includes: • Vendor/platform specific (bulk of section) • Standards • Application specific • Other (policy/political) • Ongoing section; liable (we hope!) to change for the better over time

  6. Next steps? • Comments? • Is such a case study useful? • Comments from other enterprises? • WG adoption? • Maybe whittle down or even remove ‘gaps’ section to help make the case study stand the test of time? • Abstract gaps to a separate ‘living’ ID? • Address planning was abstracted to the ‘addcon’ document (draft-ietf-v6ops-addcon-01)
