IPv6 Lab Design and Connectivity Procedures at CITC

Learn about the design of the IPv6 test lab at CITC, connectivity procedures for both CITC and client sides, subnet allocation, and application process. Understand how interested clients can connect to the lab using IPv6 over IPv4 tunnel without a dedicated link.

  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…)

  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
