  1. IPv6 Rapid Deployment on IPv4 infrastructures (6rd)‏ http://tools.ietf.org/html/draft-despres-v6ops-6rd-ipv6-rapid-deployment-00 IETF 71 - 2008-03-11 remi.despres@free.fr

  2. IETF 71 - v6ops - Rémi Després Plan • Requirements • (Actual) Rapid Deployment by FREE • ISPs that assign Private IPv4 Addresses • CPEs belonging to customers - DHCPv4 • Additional requirement ? • What next ?

  3. IETF 71 - v6ops - Rémi Després Requirements ‏ • RAPID DEPLOYMENT • No change to the core of IPv4 infrastructures • No new address assignment policy (v4 address ==> v6 site prefix)‏ • Use only v6-v4 border gateway(s) and upgraded CPEs • COMPLETENESS • IPv6 addresses MUST be as good as other native ones: guaranteed return paths (unlike 6to4)‏ • SCALABILITY • v6-v4 gateways must be stateless (like 6to4)‏ • EFFICIENCY • Direct IPv4 routes between ISP 6rd sites (like 6to4)‏ ... and KISS (Keep It Simple... Stupid‏)‏

  4. IETF 71 - v6ops - Rémi Després (Actual) Rapid Deployment by FREE • Before nov 2007: "no short term need for IPv6" • Nov 7th: 6rd principles presented to FREE (French ISP)‏ • Nov 7th at night: FREE asks for an IPv6 prefix => /32 • Nov 18th: "Done!" IPv6 prefixes confidentially available • Dec 4th: Evaluation after early trials • Dec 11th: Press release - IPv6 unicast available Opt-in service to > 1 500 000 customer sites
