Virtual Private Network (VPN)

Course Description

VPN (Virtual Private Network) technologies enable secure communication over untrusted networks by creating encrypted tunnels between endpoints. This course covers VPN protocols and implementations used in enterprise networks, from basic site-to-site connections to advanced dynamic multipoint configurations. You’ll learn IPsec fundamentals, IKE negotiation, tunnel technologies like GRE and L2TPv3, and modern VPN solutions including DMVPN, FlexVPN, and GETVPN.

Course Highlights

In this course, you will learn:

  • VPN fundamentals and use cases.
  • IPsec protocol operation including AH, ESP, and IKE.
  • IPsec tunnel mode and transport mode configurations.
  • GRE tunnels and encrypted GRE with IPsec.
  • IPsec Virtual Tunnel Interface (VTI) configurations.
  • L2TPv3 for Layer 2 VPN tunneling.
  • DMVPN phases 1, 2, and 3 configurations.
  • DMVPN with dynamic routing protocols (EIGRP, OSPF, BGP, RIP).
  • DMVPN over IPsec, dual hub designs, and QoS.
  • FlexVPN site-to-site, hub and spoke, and spoke-to-spoke topologies.
  • FlexVPN with IKEv2, PKI authentication, and smart defaults.
