1 IPv6? Agenda! IPv4 address space status! IPv6 deployment! (Short reminder on) transition techniques! IPv6 peerings at SFINX! Single IP traffic (unicast) VLAN! Conclusion 2 1
2 IPv4 address space status September 2009 IANA /8s allocation pace Year Month available /8s (IANA) 2006 September 59 Yearly consumption December September December June 39 (-2)? 11 (13)? December June September
3 Geoff Huston! APNIC! Sept. 2007! Exhaustion dates /1 5 Geoff Huston! APNIC! May 2009! Exhaustion dates /2 6 3
4 Dead lines! On September 28th 2009, exhaustion dates are forseen :! IANA: Sept. 2011! Registries (RIRs) : July 2012! Source : From the table in previous slide! 2,7 years => IANA s pool exhaustion on May (short) conclusion! If you re already working to deploy and provide IPv6 connectivity and services! Then IMHO you re in the right direction! If you re not! It s obviously wise to ask yourself if it s not time to consider this resource exhaustion seriously! Because 2 years ahead it s maybe not too long in advance to have every thing ready by the time you ll be required to be! Documentation on IPv6 deployment at IXPs! draft-ietf-v6ops-v6inixp-02.txt! And! Trainings for your operational staff! 8 4

Did you think your competitors aren t in the IPv6 race yet?! (more) Calculations! IPv6 prefix allocations increased 50% over the last 12 months! And increased 50% in EU region too! And increased 43% in France! Then you re not in an IPv6 desert! And preparing to deploy IPv6 seems not a that stupid idea than someones still use to say 16 7
8 Transition techniques short (again) reminder Terminology! Transition is a bad word! Since we re not leaving IPv4 to move to IPv6! BUT: deploying IPv6 along side IPv4! And Coexistence of the 2 IP versions will last a couple of decades? 18 8
9 Deploying IPv6 Using coexistence/transition mechanisms!! Dual Stack preferred!! IPv6 traffic is native! Encapsulation! 6(V)PE for MPLS core s! IPv6/IPv4 static + dynamic tunnels! 6to4 to be avoided (IMHO)! And replaced with 6RD but CPEs s/w has to be changed 19 Conclusion! Main goal to achieve :! Get prepared to offer IPv6 connectivity and services to your customer! Figure out what dead line suits your constraints and commercial objectives! Decide for a scenario taking into account your company constraints and specificities! Do remind:! You re not the first one running for this exercise! A lot of documentation is available on line! And plan the earliest the training of your staff 20 9
10 Bibliography Retrieving this presentation on-line: SFINX_meetg-Oct2009.pdf 21 Any questions and may be some answers 10
11 IPv6 VLAN removal on SFINX PoPs Why all this?! Initially IPv6 in a dedicated VLAN! Isolate flows of the new Internet protocol! Monitoring easier (absence of MIBs and flow monitoring solutions at this time)! Problems raised! Difficulty for customers already using same VLAN numbers on their access switches! Not homogeneous with other GIX 24 11
12 Migration not so easy! Smooth migration process chosen! New IPv6 prefix! 2001:7f8:4e::/48! In RIPE prefix dedicated for GIX! Members asked to configure new peerings on the default IPv4/IPv6 unicast VLAN and then remove former IPv6 addresses 25 A IPv6 address (/64) IPv6 address (/64) Untagged IPv6 unicast VLAN (#6) IPv4 unicast VLAN (#2) IPv6 BGP peering IPv4 BGP peering B 26 12
