BGP – Border Gateway Protocol Duration: 3 days

BGP – Border Gateway Protocol
BGP is the routing protocol used to exchange routing information between different Internet networks, e.g between a multi-homed subscriber and the ISP network. During the course theoretical presentations are mixed with practical exercises. The course covers fundamental BGP configuration as well as specific BGP issues such as creating a routing policy, building scalable BGP configurations, building a multi-homed network, getting an AS number and how to connect to an Internet exchange.

The course is targeted for people working with design, maintenance and configuration of routers in IP networks.

This course requires good TCP/IP knowledge as well as fundamental routing protocol knowledge.

This is a theoretical training with practical exercises.

NOTE: This course is not delivered with the FoldOut methodology.
