Definitive VPNs for engineers

Description

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