  1. 3rd IPv6 Task Force MeetingIPv6 lab design and connectivity proceduresCITCJanuary 20th, 2008

  2. Agenda • Explain the design of the ipv6 test lab hosted in CITC data center, focusing on the available equipment and how it is physically connected • Explain the technical requirements and procedures in order to connect to the ipv6 lab from both sides • CITC side • Client side (ISPs, government institutes, enterprises…)

  3. Table of Contents Section Name • Lab Design 1 • Connectivity Procedures 2

  6. Section Name • Lab Design 1 • Connectivity Procedures 2

  7. Connectivity Procedures Introduction • Interested clients (ISP, government institute, enterprise…) can connect to the ipv6 test lab using ipv6 over ipv4 tunnel • NO dedicated link is needed, just internet connectivity with a static IP address • Client can then test CITC ipv6 offered services (Web, DNS,…) • Multiple clients can also utilizing the CITC lab infrastructure in order to have inter-testing scenarios for certain applications

  8. Connectivity Procedures IPv6 address space • CITC have a block of ipv6 address space (2001:1490:100::/48), this block will be subnetted into smaller ipv6 subnets with prefix length of 64; the total available subnets is (2^16 =65536 subnets) • Each client will be assigned two subnets (one for the tunnel and one for internal network); So the lab can theoretically host 65536/2=32768 client • The ipv6 subnet details will be stored and maintained in following table:

  9. Connectivity Procedures Connectivity application form: • Interested client will download the application form from CITC web site, fill in required fields and submit it via email • The client should fill in the ipv4 address that will be used to terminate the ipv6ipv4 tunnel • The client will fill in also the technical contact details and email for future communication and support

  10. Connectivity Procedures Connectivity procedure (CITC): • The network administrator will received the form and check the basic ICMP (ping) connectivity with the client ipv4 address • The network administrator will then reserve and allocate two /64 ipv6 subnet for this client, and update the table mentioned early accordingly • The network administrator will create a new tunnel interface and configure a static ipv6 route for the client on the edge router (R1) • The client will receive an email of the technical details Sample configuration Cisco IOS router

  11. Connectivity Procedures Connectivity procedure (Client): Prerequisites • The ISP should have an edge router connected to the internet with a real IPv4 address • If the router is reside behind a firewall, two rules should be applied on the FW on the external interface: • Finally the cline should fill up and submit the request form Tunnel configuration: • The client now received the required technical details so he can configure and test the tunnel interface on the edge router Sample configuration Cisco IOS router
