implementing IPv6 in an ISP network, case study and lessons learned - Amos Rosenboim

  1. 1. Oasis Communication Technologies
  2. 2. Agenda • IPv6@oasis - background • Case studies: • The early days – IGLD (RIP) • Going Global – PCCW Global • End to end with no end – Xfone 018 • What have we learned ? • Technical. • Non technical.Oasis Communication Technologies
  3. 3. IPv6@oasis .Oasis is a systems integrator specializing in xSP networks  We are in business since 2006. Founded by Internet Gold  .Veterans IPv6 is both a personal passion (past), as well as a business  .(differentiator (present We spend time and money training our staff and staying up to  .date I like IPv6 because it reminds me of the early internet days Oasis Communication Technologies
  4. 4. Case studies - IGLD Back at 2003 a Cisco PLM told me how my fridge is going to refill  .itself really soon What should we do ? we asked  Start dual stack deployment now so you are ready for the massive IPv6 wave  .that is coming really really soon And so we did – we established a small IPv6 island within our  network L2TP tunnel switching to a dedicated router  IPv6 routing to 2-3 additional routers and 1 Linux server  The longest task was subneting the /32 assignment Oasis Communication Technologies
  5. 5. Case studies - IGLD In about a week we were able to ping the IPv6 internet, and even  .watch the turtle dance When we looked asides we saw no one, even when we looked  .up there was not a lot to see .But there were rumors about deployments in APAC  :What we did not do  Plan  .(‘Deploy IPv6 based services (DNS, Mail etc Oasis Communication Technologies
  6. 6. Case studies – PCCW Global.(PCCW Global is the International arm of PCCW (the incumbent player in HKG .The company operates a network that spans more than 40 countries, with ~ 70 POPs .Provides Internet transit service, MPLS VPNs, as well as voice and video services  During late2007 the company‘s management decided that full IPv6 support is . requiredby 2010.First product to support the new protocol should be internet transit I was assigned to lead the project from an engineering perspective and propose .deployment planI was the most experienced with IPv6, I already configured it on 3 routers in some small ISP in Israel,  and I was a contractorOasis Communication Technologies
  7. 7. Case studies – PCCW GlobalMy initial idea was to dual stack the entire network – we don‘t make any ? compromises, we go for the ultimate solution rightLooking at the inventory I realized that .of our routers are running old code that supports IPv6 only in theory 85% .About 60% of our deployed HW cannot forward IPv6 in HW .As it takes about 3 months to get maintenance approvals per router we‘ll be ready by 2022 or so There were some other minor issues such as: do this on the production network, but don‘t affect any ‘customers/peers etc.It was obvious we need a plan B .Thank god for islands Oasis Communication Technologies
  8. 8. Oasis Communication Technologies
  9. 9. Case studies – PCCW GlobalGreat minds think the same – It appears that the IETF actually standardized my .designThey actually made a better job than I did .It‘s called 6PE :We went ahead with the following actions .IPv6 RIR allocation request .Addressing design – both guidelines and actual sub netting .MP-BGP design .This IPv6 free core is fundamentally different than the IPv4 concept they were using .Only MPLS in the core .Much easier on the routers, less easy for NOC technicians and engineers .Think about traceroute interpretation with icmpv6 tunneling Oasis Communication Technologies
  10. 10. Case studies – PCCW GlobalWe established as much IPv6 peering as we could, but we also required some transit.We started offering IPv6 transit services Initially all L3 functions were performed on the dedicated 6PE routers After gaining some experience these routers were re purposed as IPv6 BGP RRs We started training our staff .External courses for background – only for a limited set of staff – budgetary constraints .Internal training specific to our deployment model for all relevant staff A lot of OTJT .We worked with our product team colleagues to establish the offering guidelines .They were violated by sales about 10 minutes after they were published .Many non standard customizations to support IPv6 connectivity for various customers Oasis Communication Technologies

  12. 12. Case studies – Xfone 018.Xfone 018 is a valued Oasis customer since 2008 .Oasis has built the Xfone ISP network which also carries all of their VOIP traffic .The network is built using Juniper networks HW .Oasis is also managing the network on a daily basis in an outsourcing model IPv6 project at Xfone started out of personal interest within Oasis but was soon embraced and .encouraged by Xfone managementOasis Communication Technologies
  13. 13. Case studies – Xfone 018Oasis Communication Technologies
  14. 14. Case studies – Xfone 018:Xfone deployment details 2a02:ed0::/32 assigned by RIPE 2a02:ed0::/34 Initial pool  2a02:ed0:4000::/34 reserved2a02:ed0:8000::/34 reserved 2a02:ed0:c000::/34 reserved.Customers are assigned /56 by default, /48 per request .Any router to router or LAN segment are assigned a /64, loopbacks are /128 .Separation between INFRA address space to CUST address space .OSPFv3 as IGP, MP-BGP for customer and internet routes .ND RA + DHCPv6 PD for broadband users .Control over IPv6 subscribers through RADIUS .Dual stack DNS servers and mail server .Roughly 600 active users Oasis Communication Technologies
  15. 15. Lessons learned so far - technicalMany deployment options, use the one that addresses your biggest issues use .others ad hoc.Addressing design is tricky, BCPs change frequently How to subnet my allocation ? - on nibble boundries ?What prefix length to assign .The core is easy .Access is messy Address assignment is challenging, RA alone doesn‘t work as it has no way to assign additional .configuration parameters.DHCPv6 is getting to be OK, we are almost there :Many software bugs .Client ignores prefix in RA if it‘s not a /64 .DHCPv6 implementation only handle PD DHCP requests .Data center is surprisingly good, if you choose the right vendors .Security devices performance degrade, test it as I didn‘t Oasis Communication Technologies
  16. 16. Lessons learned so far -Non technical.The number one problem for IPv6 adoption is lack of content There is no justification for this, for a content provider it‘s pretty easy to et least experiment with .ipv6Global content providers (e.g Google, Facebook, Yahoo) have been a major force behind IPv6 in .recent years, and are making a huge leap forward today? Israeli content providers :The second biggest issues is customer equipment readiness .PCs with old OS .Home routers – there are tens of thousands of unmanaged devices already deployed .Mobile phones Globally governments have been a driving force for IPv6, in Israel the government techs .and regulators are very silent about itOasis Communication Technologies
