4. Contributing Promotion of IPv6 in Asia

Why we use sTLA ?

• Current IPv6 Network– For Startup, and Try of the developping Ipv6 network

with satellite links

• Top Level Aggregater– New, Larger, And Independent Address Space got

from APNIC directly• For More Address Space

• For flexible Routing

• To operate IPv6 Network in our own policy

AI3 IPv6 Network (now)• The prefix short than /35 can’t be annouce in BGP

– RFC 2772

• We can’t annouce owr Prefix (2001:200:800::/40)– Can’t connect with APAN and Other AS.

Address Space

• Current NLA1 (2001:200:800::/40)– Many Try of the delegation way– Littele complicated – Littele address space for UDL sites

• In New Address Space– Simple delegation– Easy to operate– Enough address space for any sites / organizations

Policy

• Current Network– co-operate with WIDE is needed

• Routing

• DNS

• With own TLA– We are Independent– Operation depends on our own policy

Each Partners needs own TLA ?

• No, and It’s may be Difficult– To get TLA, the AS must have many customers

• Difference about the design of IPv4 and IPv6 address space– IPv4

• Many organization became AS for flexible routing• They got Ipv4 addresses from IR, and each of them annouced their

address space in BGP.

– IPv6• Only The AS who has many customer (customer organization) can

get the TLA• Each Organization may get /48 form TLA.• If the organization needs flexible routing, They must get

another /48 from another TLA (Multi homing)

Next → Status

Status (1)

• New Address space got from APNIC– 2001:0D30::/32

• The draft of Address assignment policy– http://sfc-cpu.ai3.net/v6/

• DNS– Reverse Address DNS delegation from APNIC

is finised

Status (2)

• External Connectivity– BGP peering of WIDE ⇔ AI3 is finished

• We use WIDE as default transit AS

– Planning to join NSPIXP6• NSPIXP6 is the testbed of IXP using IPv6

• APAN Tokyo is a member NSPIXP6

• There are other many ISPs.– Which one we connect with is not decided.

– Possibility of connecting with more than 10 ASs

IPv6 Address Assignment policy(draft, http://sfc-cpu.ai3.net/v6)

/32 /48 /64 |RRRR|TTTT|I I I I |I I I I |SSSS|SSSS|SSSS|SSSS|

• RRRR : Reserved bits (4 bits) • TTTT : Type ID(4 bits)

– "0001" for ORG– "0000" for POP (Backbone is the special case of POP)

• I I I I : Index ID of ORG and POP (8 bits)• SSSS : SLA ID (16 bits)

– Used in site(POP, ORG), at his disposal.

Tomorrow Agenda

• Address Allocation Policy• Renumbering plan• Routing design

– Between AI3 and Partners – OSPFv3– BGP4+

• Near topology with BGP confederation (but can’t annouce /32 from non-AS4717 network)

• Activating IPv6 utilization– How to use ipv6 in common ?

How to connect with UDL Partners

• This agenda belongs to UDL-WG– Needs UDLR for IPv6 for connecting without

IPv4 tunneling

• Developping of the IPv6 Testbed is not good proceeded,in many countries in Asia .

Contributing Promotion of IPv6 in Asia

• IPv6 will be important in Asia to use enough global addresses (in near future)

• AI3 has …– experience of Developping IPv6 Testbed– And New Large Address Space– And we will get full operational tecnology

throught the operaiton of sTLA

Idea• Providing Free IPv6 Connectivity for non-

partner Organizations in Asia. – Using any current connectivity include IPv4

Tunneling

• Well browse capable IPv6 Network – Make our operation information Public in WWW

• Router infomation and configuration• Network monitoring• Address Allocation• Security• Server configuration• External Connectivity

Image (sample)

• All AI3 Partners, and UDL Partners is connected by ipv6 in nature.

• Any organization is asia can get Ipv6 address and connect to our ipv6 network, with application

– If there is domestic AI3 POP, they connect to that.– If ther is no domestic POPs, sfc will support them

Merit• Any Organization in Asia can connect to

global IPv6 network through AI3.• And They can get the operational technology

from real ipv6 network• The active network whoes setting and

operational policy can be browsed shall be a great reference for most peaple. It’s useful.

• We can provide them , more than free IPv6 connectivity!

problem

• Security Issue– We must protect our network, from many peaple.– Many peaple will connect to internal of AI3 in

IPv6

• Bandwidth Problem– Let non-partner ORGs IPv6 test traffic not to

press our commodity /experimental traffic

Tomorrow Agenda

• Address Allocation Policy

• Renumbering plan

• Routing design– Internal Connectivity– BGP4+/OSPFv3

• Activating IPv6 utilization– How to use ipv6 in commodity ?

+ Our stance about contributing promotion of IPv6 in Asia
