LINX Accredited Internet Technician 3  |    A 5 day   hands on   training course

LINX 3 training course description

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.

  • Describe how BGP works.
  • List, describe and configure the main BGP attributes.
  • Implement and troubleshoot BGP.
  • Work with route aggregation and calculate CIDR prefixes in seconds.
  • Influence traffic paths with BGP.
  • Implement and troubleshoot MPLS.
