Total OSPF for engineers

A 3 day
HANDS ON
training course

OSPF training course description

A detailed hands on examination of OSPF. Hands on sessions are used to reinforce the theory rather than teach specific manufacturer equipment. The course starts with a recap of reading routing tables and then jumps straight in with simple OSPF configuration. OSPF features are then studied and configured before moving onto how OSPF works within an area. Multi area OSPF is then studied before looking at OSPF operation in detail by analysing OSPF packets. Finally areas are covered again in more detail followed by troubleshooting.

Key outcomes from this course

By the end of the course delegates will be able to:
  • Design OSPF networks.
  • Design IP addressing schemes suitable for route summarisation.
  • Troubleshoot OSPF networks.
  • Describe the operation of OSPF.

OSPF training course details

TCP/IP Foundation.
Duration:
3 days

Training approach

This structured training course seeks to build upon workbook learning through the use of group exercises, dynamic discussion and individual tasks in order to deliver an engaging and interactive module that will ensure all candidates are able to transfer their new skills into the workplace.

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.
