Total OSPF for engineers

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.
