1. Implementing Advanced Services Today: IPv6 Atlanta Guy Almes on behalf of the Internet2 IPv6 WG 30 May 2000

2. Outline of Talk A IPv6 and its role within Internet2 A The emerging Internet2 IPv6 Infrastructure A Internet2 IPv6 WG Activities

3. IPv6 and its role within Internet2 A "Next Generation" of the IP protocol A Resulted from extensive process during the mid 1990s A Two explanations for why IPv6 is important

4. Explanation #1 A Address Space Exhaustion • IETF Road Working Group of 1992 • CIDR as the 'answer' • Then five years of Internet growth • Multihoming and the breakdown of civic virtue • 802.11 • 3G cell phones • Maybe we do care...

5. Explanation #2 A A conservative/tasteful iteration on the IPv4 design • Mobility • Multicast and Anycast • Public and private addresses • IPsec A End to End Transparency A Global Addresses

6. What are the alternatives? A Balkanization of the Internet • firewalls and VPNs A NATs • breaks end-to-end transparency • some applications will not work in this environment

7. The emerging Internet2 IPv6 Infrastructure A Both backbones support • vBNS: IPv6 over ATM • Abilene: IPv6 over IPv4 A Provisionally COU-free A Peers with the 6TAP for international transit

8. Abilene IPv6 Backbone A Cisco 7200 routers: • Atlanta, hosted by the SoX • Colorado, hosted by the Front Range GigaPoP • Indianapolis, hosted by Indiana University • Pittsburgh, hosted by PSC • Full mesh of IPv6-over-IPv4 tunnels A 24-by-7 support by the Abilene NOC • Grover Browning

10. How to play on your campus or gigaPoP A Engage the IPv6 WG • Addressing • Tunneling to the appropriate backbone (or gigaPoP) IPv6 router • Support DNS etc A Reach out to the Comp or Elec departments

11. Addressing UCAID (ABILENE> 3025 Boardwalk, Suite 100 Ann Arbor, MI 48108 US Netname: ABILENE Netnumber: 2001:0468:0000:0000:0000:0000:0000:0000/35 Coordinator: Finkelson, Dale (DF90-ARIN) dmf@UNL.EDU

12. Supported Routers A Cisco • IOS 12.2T A Unix and Zebra • *bsd and Linux A Others

13. Hosts A *bsd A Linux A Windows 2000 A others

14. IPv6 Working Group  Dale Finkelson Michael Lambert A Engineering/coordination A Education/training A Exploring the motivation

15. Spreading the Word A First IPv6 Workshop • May 2001, Univ Nebraska A Planning to support about 8-10 per year A Attend/plan

16. Examining the Motivation A Why should our community care? • IPv6 preserves end-to-end transparency • improved support for mobility • key for IPsec • key for the scalability of the Internet • when sites are not pure 'clients' " peer to peer " conferencing among three or more sites " SIP IP telephony A The answers must be pragmatic.
