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.

What is policy? Examples, route filtering, AS
filtering, regular expressions, applying preference

"Very relevant skills focused training."
"It is a good base level BGP training to participate at LINX and essential for all LINX staff."
This structured training course seeks to build upon workbook learning through the use of group exercises, dynamic discussion and individual tasks in order to deliver an engaging and interactive module that will ensure all candidates are able to transfer their new skills into the workplace.
