A detailed study of BGP and core MPLS, from the basics of how it works through to advanced issues such as route reflectors, policy, filtering, route selection and routing registries. Practical hands on with Cisco routers follow the major sessions to reinforce the theory. Juniper configurations are also explored in the theory sessions.
