Definitive IP VPNs for engineers

A 3 day
training course
**Due to the current COVID-19 isolation rules all our courses are being delivered via virtual instructor led learning until further notice**

VPN training course description

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.

Key outcomes from this course

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.

Training approach

This structured course uses Instructor Led Training to provide the best possible learning experience. Small class sizes ensure students benefit from our engaging and interactive style of teaching with delegates encouraged to ask questions throughout the course. Quizzes follow each major section allowing checking of learning. Hands on sessions are used throughout to allow delegates to consolidate their new skills.

Why Choose Us

SNT trainers score an average of over 90% on the three main areas of:
  • Ability to teach
  • Technical knowledge
  • Answering questions
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM

We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
