BGP-4 is the routing protocol of choice today when large amounts of routing information need to be handled. It is used by Internet service providers both between the autonomous systems (AS) and within the AS. BGP-4 also plays an important role in connecting large customers with multi-homing. Participants in this course will gain experience in the use of BGP-4, which can be directly applied when setting up and optimizing their own network. In doing so, they will acquire the skills required for independent network configuration for successful Internet routing, which is also required when setting up and operating an MPLS-based VPN backbone.
