AARNet Copyright 2007 AARNet IPv 6 Update IPv 6 Workshop APAN 24, Xi’An 2007 Bruce Morgan

AARNet Copyright 2007 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-64 c (10 Gbps) links connect major capital cities with routing being done by Juniper M 320 routers 2

AARNet Copyright 2007 University connections • Universities are encouraged to have diverse connections to the Juniper M 320 routers at each Po. P. • 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. 3

AARNet Copyright 2007 The international footprint • AARNet has a very large international footprint from the Po. P 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), Any 2 (LA) – Singapore, Frankfurt (DE-CIX), Amsterdam (AMS-IX), London (LINX) 7 • Currently 622 Mbps to Singapore and then on to Frankfurt • The 622 Mbps link to Singapore connects to the

AARNet Copyright 2007 10 G Trans Pacific • • Partnership with Southern Cross Cable Networks AUP - Research and Education only Dual STM-64 c (OC 192) Northern path to Seattle – Layer 3 routed • Southern path to Los Angeles – Layer 1/2 • Catalyse Global Astronomy Initiative – Mauna Kea, Big Island 8

AARNet Copyright 2007 TEIN 2 Connectivity § There are four STM-1 circuits linking Perth to Singapore. § Two of these go via APCN, and the other two via SMW 3 to provide diversity and fault tolerance 9 § AARNet Singapore Po. P establish at the Kim Chuan data centre from where we peer with TEIN 2, Singaren and ASNet

AARNet Copyright 2007 Commodity and R&E 10 • 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 L 2 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

AARNet Copyright 2007 AARNet support for IPv 6 • AARNet 3 core and edge is dual stack since 2003 • Dual stack deployed across M 320 core using OSPF 3 and BGP as routing protocols • IPv 6 is used within AARNet – www. aarnet. edu. au IPv 6 enabled – Infrastructure is IPv 6 enabled • IPv 6 Multicast is enabled – SSM supported – Currently use a static RP for ASM 11

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

AARNet Copyright 2007 AARNet Migration Broker • • • 13 http: //broker. aarnet. au Hexago appliance Same as Freenet 6 Tunnel Setup Protocol NAT Traversal support Open to anyone who can reach it via a domestic Australian path

AARNet Copyright 2007 Peering and Transit • International transit and peering available for IPv 6 • Encouraging both IPv 4 and IPv 6 peering – But still many IPv 4 only peers – Haven’t yet fully deployed RPSLng so IPv 6 prefix filtering not as strong in the IPv 4 world 14

AARNet Copyright 2007 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 15

AARNet Copyright 2007 Still work to be done… • DNS about to be implemented • Mail issues – 3 rd parties? • Still need to deploy IPv 6 measurement – IPv 6 monitoring is still in its infancy within our infrastructure – IPv 4 Netflow is heavily deployed – IPv 6 isn’t at the moment 16

AARNet Copyright 2007 AARNet 3 is ready… • A few institutions are using IPv 6 natively in a limited fashion – Many are worried about deploying a dual stack at the edge • Stability/complexity concerns – Existing infrastructure may not support IPv 6 • Firewalls • Web services • Some institutions and researchers use static tunnels or broker 17

AARNet Copyright 2007 Some progress… • Fiji is now advertising IPv 6 routes • More customers are deploying IPv 6 – But still a snail’s pace • Uptake of IPv 6 has been slow – Lack of IPv 6 specific spplications – Not a huge amount of IPv 6 services available – No shortage of IPv 4 address space within institutions – Legacy and non-IPv 6 compliant equipment – Security – Management 18

AARNet Copyright 2007 IPv 4 address depletion • • • 19 2009? 2012? 2015? When will it kick in? Will it effect our customers/institutions immediately? Will it be a painful process?

AARNet Copyright 2007 Where to from here? Ensure as many services as possible are IPv 6 enabled • Encourage customer connections • Look for more peering opportunities • Encourage IPv 6 activities – Education on setting up IPv 6 to institutions 20
