1. AARNet Copyright 2007 AARNet IPv6 Update IPv6 Workshop APAN 24, Xi’An 2007 Bruce Morgan

2. AARNet Copyright 2007 2 The AARNet Network AARNet owns and operates a resilient and redundant multi- Gbps network across Australia. In the Eastern Australia we have deployed DWDM equipment which currently has up to 320 Gbps capacity. Dual STM-64c (10 Gbps) links connect major capital cities with routing being done by Juniper M320 routers

3. AARNet Copyright 2007 3 University connections Universities are encouraged to have diverse connections to the Juniper M320 routers at each PoP. Institutions typically connect at 1 Gbps and we have deployed Cisco 7304 routers at each site (edge routers), and also edge servers. This allows close monitoring of each tail circuit. So far about 85 edge routers have been deployed.

5. AARNet Copyright 2007 5 Regional Optical Network

6. AARNet Copyright 2007 6 AARNet International Network

7. AARNet Copyright 2007 7 The international footprint AARNet has a very large international footprint from the PoP in Frankfurt, Germany to Palo Alto in the US - it covers a timezone difference of 17 hours from +1 to -8 Peering at : –Hawai’I, Seattle (Pacific Wave), PAIX, Telehouse (LA), Any2 (LA) –Singapore, Frankfurt (DE-CIX), Amsterdam (AMS-IX), London (LINX) Currently 622 Mbps to Singapore and then on to Frankfurt The 622 Mbps link to Singapore connects to the TEIN2 nework

8. AARNet Copyright 2007 8 10G Trans Pacific Partnership with Southern Cross Cable Networks AUP - Research and Education only Dual STM-64c (OC192) Northern path to Seattle –Layer 3 routed Southern path to Los Angeles –Layer 1/2 Catalyse Global Astronomy Initiative –Mauna Kea, Big Island

9. AARNet Copyright 2007 9 TEIN2 Connectivity  There are four STM-1 circuits linking Perth to Singapore.  Two of these go via APCN, and the other two via SMW3 to provide diversity and fault tolerance  AARNet Singapore PoP establish at the Kim Chuan data centre from where we peer with TEIN2, Singaren and ASNet

10. AARNet Copyright 2007 10 Commodity and R&E AARNet offers both commodity (commercial) internet and research networking Two 10 Gbps circuits for R&E connectivity to the US. The northern link is IP and routed - the southern link will be presented as light paths (ethernet L2 circuits) 6 x STM-4 (3.6 Gbps) circuits to the US - terminating at Palo Alto and Los Angeles 2 x STM-1 (310 Mbps) circuits to Seattle via Hawai’i and Fiji 4 x STM-1 (622 Mbps) circuits to Singapore and Frankfurt – also two 100 Mbps circuits to LINX and AMS-IX

11. AARNet Copyright 2007 11 AARNet support for IPv6 AARNet3 core and edge is dual stack since 2003 Dual stack deployed across M320 core using OSPF3 and BGP as routing protocols IPv6 is used within AARNet –www.aarnet.edu.au IPv6 enabledwww.aarnet.edu.au –Infrastructure is IPv6 enabled IPv6 Multicast is enabled –SSM supported –Currently use a static RP for ASM

12. AARNet Copyright 2007 12 Addressing Addressing Plan –Currently use /32 2001:388::/32 allocated by APNIC Allocate a /40 to a PoP or a /48 to a customer A /39 is allocated to the Tunnel broker networks Some customers have their own allocations

13. AARNet Copyright 2007 13 AARNet Migration Broker http://broker.aarnet.net.au Hexago appliance Same as Freenet6 Tunnel Setup Protocol NAT Traversal support Open to anyone who can reach it via a domestic Australian path

14. AARNet Copyright 2007 14 Peering and Transit International transit and peering available for IPv6 Encouraging both IPv4 and IPv6 peering –But still many IPv4 only peers –Haven’t yet fully deployed RPSLng so IPv6 prefix filtering not as strong in the IPv4 world

15. AARNet Copyright 2007 15 The customer edge All customers can connect natively –But the customer edge is configured only on request –CPE router dual stack but customer’s router/firewall may not be

16. AARNet Copyright 2007 16 Still work to be done… DNS about to be implemented Mail issues – 3 rd parties? Still need to deploy IPv6 measurement –IPv6 monitoring is still in its infancy within our infrastructure –IPv4 Netflow is heavily deployed – IPv6 isn’t at the moment

17. AARNet Copyright 2007 17 AARNet3 is ready… A few institutions are using IPv6 natively in a limited fashion –Many are worried about deploying a dual stack at the edge Stability/complexity concerns –Existing infrastructure may not support IPv6 Firewalls Web services Some institutions and researchers use static tunnels or broker

18. AARNet Copyright 2007 18 Some progress… Fiji is now advertising IPv6 routes More customers are deploying IPv6 –But still a snail’s pace Uptake of IPv6 has been slow –Lack of IPv6 specific spplications –Not a huge amount of IPv6 services available –No shortage of IPv4 address space within institutions –Legacy and non-IPv6 compliant equipment –Security –Management

19. AARNet Copyright 2007 19 IPv4 address depletion 2009? 2012? 2015? When will it kick in? Will it effect our customers/institutions immediately? Will it be a painful process?

20. AARNet Copyright 2007 20 Where to from here? Ensure as many services as possible are IPv6 enabled Encourage customer connections Look for more peering opportunities Encourage IPv6 activities –Education on setting up IPv6 to institutions
