Large IPv6 Allocations
• IPv6 allocations to IPv4 networks• /28 JP - VECTANTNET
• Expansion of the initial alloc space forexisting v6
• /21 + /30 JP (kept initial /30) - NTT• /20 AU (renumbering initial /32) - Telstra
IPv6 Implementation (Telstra)
• What is the current status of IPv6 roll-outand future deployment plans?
• Enable ipv6 on Network Core- Dual stacked core (v6 & v4 ships in the night routing)- /64 for loopbacks, for PtP links and LANs- Deploy IPv6 enabled IGP (IS-IS or OSPFv3) for
topology distribution- Use MBGP4+ address family ipv6 for prefix
distribution- Follow existing IPv4 routing policies and practices
IPv6 Implementation (Telstra)
• What is the current status of IPv6 roll-outand future deployment plans?
• Enable selected edge boxes for dual stackedconnection- IPv6 native from client service to network edge(supported over Ethernet, POS, ATM, Frame, Serial)- Deploy tunnel terminators on each POP (clients thatcannot have native connections can 'ipv6ip' tunnel totheir local POP, this avoids un-necessary overlaytunnels)- Acquire multiple tunneled transit paths until native isoffered (native IPv6 to US/Europe currently an issue)

• What is the current status of IPv6 roll-out and future deployment plans?
• Once National Network is IPv6 enabled &bedded down- 6 month timeframe- Push into internal product groups ( whenIPv6 is enabled, barrier to entry for internalproduct groups is reduced such asconsumer broadband products DSL/Cableand 3G Mobiles)
IPv6 Implementation (Telstra)Cont…
• What are the issues/difficulties?• Have to logically rebuild the entire network in IPv6
- Operationally the existing topology needs to berecreated in IPv6- Separate IPv6 IGP needs to be deterministically setto recreate existing ipv4 forwarding paths- Operationally very difficult to debug if forwardingpath behaviours differ between v4 & v6 protocols- More skill-set and training required foroperational
• Upgrade operational systems to allow customer IPv6prefixes- Allow AAAA records in DNS via client GUI- Integrate IPv6 syntax in IP allocation systems
Experimental Allocations
• Experimental Networks• /32 Allocation for WIDE Japan
– IPv6 allocation for a field test of v6 DNS servicewith anycasting
• Document of the experiment will soon bepublished at the following URL:http://www.apnic.net/services/ipv6_guide.html
