  1. Interop LabsVPN Interoperability Demo Las Vegas, Nevada May, 1999

  2. VPN Interoperability:What are you seeing? • World’s Largest Public VPN Interoperability Demonstration • All IPSEC (IP Security) compliant • All using IKE/ISAKMP (Internet Key Exchange)

  3. VPN Interoperability:What are you not seeing? • Not every product supports the same set of SA establishment profiles • 3DES versus DES • Subnet versus Host-based SAs • ISAKMP versus IPSEC profile sets • Not all SW versions seen here are shipping/released • SA re-establishment not well defined

  4. VPN Interoperability:What are the pieces? • 12 vendors • 65 site-to-site tunnels • IP traffic with TCP and UDP • ESP Tunneling Encryption • Authentication within ESP • IKE/ISAKMP key management with preshared secrets

  5. VPN Interoperability:Why is this interesting? • Vendor independent VPN • You need not be locked into a single vendor solution for VPNs any more! • You can talk to other enterprises who have already chosen a VPN vendor • Product flexibility • Not every vendor has every answer • Mix and match to fit your needs • Standards Assurance • Vendors who successfully interoperate will not lead you down a proprietary path

  6. VPN Interoperability:How did we do it? • Step1: Start with a public LAN Router

  7. VPN Interoperability:How we did it: Step 2 • Add VPN vendors LAN A LAN B VPN A device VPN B device Router VPN C device VPN D device VPN E device LAN C LAN D LAN E Mgmt station Mgmt station Mgmt station

  8. VPN Interoperability:How we did it: Step 3 • Add Connectivity Testers Conn. Tester LAN A LAN B Conn. Tester VPN A device VPN B device Router VPN C device VPN D device VPN E device LAN C LAN D LAN E Mgmt station Conn. Tester Conn. Tester Mgmt station Conn. Tester Mgmt station

  9. VPN Interoperability:How we did it: Step 4 • Verify VPNs Conn. Tester LAN A LAN B Conn. Tester VPN A device VPN B device Router VPN C device VPN D device VPN E device LAN C LAN D LAN E Mgmt station Conn. Tester Conn. Tester Mgmt station Conn. Tester Mgmt station

  10. VPN Interoperability:How did we do it? Conn. Tester 1. Connectivity Tester on VPN B sends a packet to Connectivity Tester on VPN E 5. B Tester receives response and updates web page LAN B VPN B device 2. VPN B device tunnels packet in IPSEC and sends to VPN E device VPN E device 3. VPN E device de-tunnels packet and sends to Connectivity Tester on VPN E LAN E 4. Connectivity Tester on VPN E receives packet and sends response to Connectivity Tester on VPN B Conn. Tester Mgmt station

  11. VPN Interoperability:See 12 VPNs in Operation Nortel Timestep Cisco RadGuard VPNet Internet Dynamics Microsoft FreeS/WAN Checkpoint Data Fellows Intel RedCreek

  12. Each VPN has a VPN device and Connectivity Tester Some also have management stations in the iLabs Connectivity Tester Management Station VPN Device

  13. VPN Interoperability:VPN Device connections • VPN Devices have two connections • One to its private network (unencrypted clients/servers) • One to the public network (encrypted traffic only) • Connectivity Tester is on the private network

  14. VPN Interoperability:Connectivity Tester The Connectivity Tester on each LAN shows VPN encrypted connectivity between vendors. Vendor logos indicate a successful tunnel between this tester and the other products shown

  15. VPN Interoperability:Protocol Analysis • W W G and Shomiti protocol analyzers are available to watch IPSEC SA establishment

  16. VPN Interoperability:Participating VPN Products (1 of 2)
