Total BGP for engineers

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.
