Definitive IP routing for engineers

A 5 day
training course

Definitive IP routing course description

An intensive hands on IP routing course leading to LINX Accredited Internet Technician stage 2 focusing on routing in an IP environment. The course concentrates on OSPF and IS-IS but also covers STP and VLANS. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment.

A multiple choice exam, leading to the LAIT II certification, is included at the end of the course. The exam consists of 60 questions and lasts 2.0 hours.

Key outcomes from this course

By the end of the course delegates will be able to:
  • Calculate subnet numbers in seconds.
  • Configure and troubleshoot static routes.
  • Explain how OSPF works.
  • Build resilient networks with VRRP and OSPF.
  • Implement and troubleshoot OSPF, IS-IS and VLANS.
  • Evaluate and choose appropriate routing protocols for particular scenarios.

An optional multiple choice exam, leading to the LAIT II certification, is included at the end of the course. The exam consists of 60 questions and lasts 2.0 hours.

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.
