  1. Establishment of IPv6 Enabled Test Bed at ERNET Dipak Singh ERNET India deepak@eis.ernet.in

  2. The Agenda • Objective of the Project “Establishment of IPv6 Enabled Testbed at ERNET”. • Benefits of the Project. • Achievements so far. • Pending work. ERNET India

  3. The Project • The project was sanctioned by DIT in March 2004 to be implemented by ERNET India and IIT Kanpur jointly. • The duration is for 1 year • The total budget outlay is Rs. 2.50 crore. ERNET India

  4. Objective of Project • To setup IPv6 Test Bed at ERNET Backbone • Setup IPv6 Domain Name Server & IPv6 Mail Server at all PoP locations and test Mail Services using IPv6. • To Demonstrate following features - • Plug ‘n’ Play (Auto-configuration) • Multicasting • QoS • Development of IPv6 Portal. • Organizing an IPv6 workshop for participants from academia and industry. ERNET India

  5. Benefits of IPv6 Test bed • Provide hands-on experience in managing a IPv6 network and system management. • Gain experience of implementing various transition mechanisms. • Define a seamless migration from IPv4 to IPv6. • ERNET (along with IIT Kanpur) can train ISPs and other networking professionals in implementing IPv6 in their network. • Educational Institutions will be allotted more nos. of IP Addresses. • Test Bed will facilitate R&D in this area. ERNET India

  6. ERNET • ERNET is a dedicated network for Education and Research Institutions. • It connects premier educational and research institutes in the country • ERNET was the first to bring Internet to India • It has almost 20 year’s experience of managing a network • ERNET has a presence across the nation • 13 Points of Presence (POPs) • Mix of Terrestrial and Satellite Network ERNET India

  7. Growth of ERNET • ERNET started with Dial-up network in 1986-87. • Initially UUCP mail was only service started by ERNET. • First leased line of 9.6 kbps was installed in Jan’1991 between Delhi and Mumbai. • ERNET was alloted Class B IP address 144.16.0.0 by InterNIC in 1990. Subsquently Class C addresses were alloted to ERNET by APNIC. • All IITs, IISc Bangalore, DOE Delhi and NCST Mumbai were connected by 9.6 kbps leased line by 1992. • In 1992, 64 kbps Internet gateway link was commissioned from NCST Mumbai to UUNet in Virginia near Washington DC. ERNET India

  8. Growth of ERNET • In 1998 ERNET India was registered as Autonomous Society. • In 1999-2000 new terrestrial high speed backbone was setup. • In 2000 POP infrastructure was upgraded. • Satellite WAN was setup in 1993. ERNET India

  9. ERNET as on Today • 1100 institutes are ERNET users under different schemes • UGC Infonet • AICTE Scheme • Navodaya Vidyalaya Samiti (NVS) • ICAR net • Vidya Vahini ERNET India

  10. ERNET as on Today(contd.) Managing such a large network with a small number of IPv4 addresses is very difficult in future and IPv6 is solution. ERNET India

  11. 2 Mbps Line 8 Mbps Line 1 - 7 Gateway Links 1 ERNET Backbone IPV4 Enabled Delhi Guwahati Kanpur 4 Calcutta OSPF 2 Bhubneshwar Mumbai Indore Pune 5 3 Hyderabad 7 6 Chennai Bangalore ERNET India Satellite PoPs

  12. Infrastructure Upgradation • Hardware & IOS of Routers at following PoP locations has been upgraded to support dual stack 1. ERNET HQ Delhi (Cisco 7507) 2. IISc Banglore (Cisco 7507) 3. ERNET HUB Banglore (Cisco 7507) 4. IIT Chennai (Cisco 7507) 5. CDAC Mumbai (Cisco 7507) 6. IUCAA Pune (Cisco 7507) 7. IIT Kanpur (Cisco 7206) 8. University of Hyderabad (Cisco 7206) 9. VECC Kolkata (Cisco 7206) • A separate LAN segment for IPv6 has been created at each POP and an IPv6 server has been deployed. ERNET India

  13. Router Upgradation & Routing • To deploy IPv6, we had following options • Tunneling, Native IPv6 and Dual Stack • Dual Stack of IPv4 and IPv6 has been deployed over ERNET backbone. • IPv4 and IPv6 routing are running simultaneously. • For Intra-AS routing, protocol options are • RIP, OSPF, IS-IS • OSPFv3 for IPv6 was deployed as OSPF for IPv4 was already running. ERNET India

  14. Configuring IPv6 Routing • Enabling IPv6 Routing del-br(config)# ipv6 unicast-routing • Enabling OSPFv3 del-br(config)# ipv6 router ospf 2698 del-br(config-rtr)# area 0 range 2001:E30::/40 del-br(config-rtr)# area 1 range 2001:E30:1800::/40 • Checking OSPFv3 del-br#sh ipv6 ospf 2698 It will give information about OSPFv3 Process, Router ID, Area and other OSPF related information. ERNET India

  15. del-br#sh ipv6 ospf 2698 Routing Process "ospfv3 2698" with ID 202.141.144.254 It is an area border router SPF schedule delay 5 secs, Hold time between two SPFs 10 secs Minimum LSA interval 5 secs. Minimum LSA arrival 1 secs LSA group pacing timer 240 secs Interface flood pacing timer 33 msecs Retransmission pacing timer 66 msecs Number of external LSA 0. Checksum Sum 0x000000 Number of areas in this router is 2. 2 normal 0 stub 0 nssa Area BACKBONE(0) Number of interfaces in this area is 6 SPF algorithm executed 612 times Area ranges are 2001:E30::/40 Active(192) Advertise Number of LSA 92.

  16. Enabling IPv6 on individual interfaces del-br(config)#int s1/1/1 del-br(config-if)#ipv6 address 2001:0E30::5/126 del-br(config-if)#ipv6 ospf 2698 area 0 • del-br#sh ipv6 int s1/1/1 Serial1/1/1 is up, line protocol is up IPv6 is enabled, link-local address is FE80::201:64FF:FEEF:B008 Description: ## Mumbai-I ## Global unicast address(es): 2001:E30::5, subnet is 2001:E30::4/126 Joined group address(es): FF02::1 FF02::2 FF02::5 FF02::D FF02::16 FF02::1:FF00:5 FF02::1:FFEF:B008 MTU is 1500 bytes ICMP error messages limited to one every 100 milliseconds ICMP redirects are enabled ND DAD is enabled, number of DAD attempts: 1 ND reachable time is 30000 milliseconds Hosts use stateless autoconfig for addresses. ERNET India

  17.

  19. IPv6 Enabled ERNET Backbone Delhi Backbone IPv6 Addresses 2001:0E30::/40 2001:0E30::22/126 2001:0E30::5/126 ::21 Kanpur ::13 2001:0E30::6/126 Backbone Area 0 2001:0E30::18/126 Mumbai Kolkata OSPFv3 2001:0E30::57/126 ::198 ::58 Pune Hyderabad ::197 2001:0E30::101/126 ::178 ::126 ::125 ::177 2001:0E30::102/126 Chennai ::130 ::129 ::14 IISC ::137 VSAT HUB ::138 ERNET India

  20. OSPFv3/OSPFv2 Differences • OSPFv3 runs on per-physical link rather than IP Subnet in OSPFv2 • Removal of Addressing semantics. • OSPFv3 supports Multiple instances per link • Router Id, Area Id and LSA Id are still 32-bit number • Neighbors are always identified by Router ID ERNET India

  21. IPv6 Addressing Scheme • The following IPv6 prefixes have been assigned to ERNET by APNIC:2001:0E30::/32 • ERNET PoPs are being assigned to /40 prefixes. ERNET India

  22. IPv6 Addressing Scheme (contd.) • Terrestrial Network: • ERNET Delhi HQ = 2001:0E30:1800::/40 • IIT Kanpur = 2001:0E30:1400::/40 • CDAC-Mumbai = 2001:0E30:1C00::/40 • IISC Banglore = 2001:0E30:2000::/40 • IUCAA Pune = 2001:0E30:2400::/40 • Univ. of Hyderabad = 2001:0E30:2C00::/40 • IIT Chennai = 2001:0E30:3000::/40 • VECC Kolkata = 2001:0E30:3400::/40 • VSAT Network: • ERNET Hub Banglore = 2001:0E30:2800::/40 ERNET India

  23. IPv6 Addressing Scheme (contd.) • Based on the above a PoP can further distribute /48 addresses to its customers.(1208925819614629174706176) • For example following IPV6 Addresses are proposed to be given for ERNET Delhi PoP users - • Delhi University = 2001:0E30:1801::/48 • JNU = 2001:0E30:1802::/48 • Univ. of Rajasthan = 2001:0E30:1803::/48 .. and so on ERNET India

  24. Services Planned • IIT Kanpur will act as Mail Gateway for incoming and outgoing mails from ERNET. • The individual Mail Servers at each PoP will forward and receive mails from Mail Gateway. • All Mail Servers except at Kanpur will have static IPv6. Mail server at Kanpur will have both IPv4 and IPv6 addresses. • The mail flow from the IPv6 Mail Gateway to the Internet will be on IPv4. • The mail transaction among mail servers will be on IPv6 only. • The mail transaction between mail server and mail clients can be on IPv6 or IPv4 depending on whether the client is IPv6 or IPv4. • Multicasting across 9 POPs. ERNET India

  25. IPv6 Domains • All the PoPs being enabled for IPv6 will have a following subdomain for IPv6 applications • ERNET Delhi ipv6.eis.ernet.in • IIT Kanpur ipv6.iitk.ernet.in • CDAC Mumbai ipv6.ncst.ernet.in • IISC Bangalore ipv6.iisc.ernet.in • HUB Bangalore ipv6.hub.ernet.in • Univ. of Hyderabad ipv6.uohyd.ernet.in • IUCAA Pune ipv6.iucaa.ernet.in • IIT Chennai ipv6.iitm.ernet.in • VECC Kolkatta ipv6.veccal.ernet.in ERNET India

  26. Service Deployed • IPv6 server has been configured at ERNET Hq Delhi and IIT Kanpur. • Server at other POPs are yet to be configured. • Mails between Kanpur and Delhi are running over IPv6. • Multicasting has been tested at Delhi locally. • It is yet to be tested across Delhi and Kanpur • Auto-configuration feature has been tested in Windows XP/2K3 and Linux OS. ERNET India
