A detailed study of BGP, from the basics of how it works through to advanced issues such as route reflectors, policy, filtering, route selection and routing registries. The course culminates with a study of an industrial strength BGP template illustrating important issues such as bogon filtering. Practical hands on with routers follow the major sessions to reinforce the theory.
A multiple choice exam, leading to the LAIT III certification, is included at the end of the course. The exam consists of 60 questions and lasts 2 hours.
