A hands on course covering IP VPNs from the basics of benefits and Internet vs. Intranet VPNs through to detailed analysis of the technologies involved in IP VPNs. All the major VPN protocols are covered including PPPoE, L2TP, SSL, IPsec and dynamic VPNs. MPLS L3 VPNs are also covered.

TCP/IP foundation for engineers

IP Security foundation for engineers

By the end of the course delegates will be able to:

Describe what an IP VPN is and explain the difference between different VPN types.
Recognise the design and implementation issues involved in implementing an IP VPN.
Explain how the various technologies involved in an IP VPN work.
Describe and implement: L2TP, IPsec, SSL, MPLS L3 VPNs.
Evaluate VPN technologies.
