CTBC AS27664 IPv6 StrategyDecisions:✔ To implement native IPv6 in the logical infrastructureDependency on native IPv6 peering and transit establishment.Avoid tunnels use.✔ To provide Internet access in dual stack modeLACNIC XI – FLIP-6 - IPv6 Implementation Case Study at São Paulo / Brazil - CTBC (AS27664) - Eduardo Ascenço Reis - 2008-05-29 11


CTBC AS27664 IPv6 Recent History (2008) 1/2●On January 2008, CTBC asked for and received the IPv6 CIDR 2001:1290::/32 allocationfrom Registro.br (BR NIR).●IPv6 implementation on Backbone and access networks.●Activation of the first customer in dual stack mode:my personal workstation (2Mbps dedicated Internet access)●Changed its Gigabit Ethernet connection to PTTmetro (NIC.br IXP - http://sp.ptt.br/) from accessto trunk and enabled the IPv6 VLAN.●Established IPv6 peering with Registro.br (AS22548) and RNP (AS1916) by PTTmetro PIX.●External IPv6 tests and use – DNS resolution and Registro.br registration services.●Enabled IPv6 transit with Global Crossing (AS3549) extending its IPv6 connectivity to the Internet.●Performed basic Internet IPv6 real tests:Identified some initial connectivity problems (higher latency to some sites compared to IPv4)Identified some IPv6 security exposure vulnerabilitiesNext Brazilian Security Working Group Meeting (GTS-11 - http://gts.nic.br/) on 1 Jun 2008LACNIC XI – FLIP-6 - IPv6 Implementation Case Study at São Paulo / Brazil - CTBC (AS27664) - Eduardo Ascenço Reis - 2008-05-29 12

CTBC AS27664 IPv6 – Some Concerns●IPv6 implementation demands time which means cost●Few Brazilian NSP/ISP to exchange IPv6 traffic●Connectivity tests shows quality difference between IPv4 and IPv6 of some international sitesMaybe related with tunnels use and/or suboptimal IPv6 traffic engineering●Google search for IPv6 shows lots of URL about how to disable IPv6 in order toincrease Internet performance for different end users systems (Windows, Linux, etc)LACNIC XI – FLIP-6 - IPv6 Implementation Case Study at São Paulo / Brazil - CTBC (AS27664) - Eduardo Ascenço Reis - 2008-05-29 22
