BGP TRAINING COURSE DESCRIPTION
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 available
after the course. The exam consists of 60 questions and lasts 2 hours.
