| Summary

BGP defines the basis of routing architectures in the Internet. The segregation of networks into autonomous systems has logically defined the administrative and political borders between organizations. Interior Gateway Protocols can now run independently of each other, but still interconnect by way of BGP to provide global routing.

In this module, the details of the practical implementation for BGP as part of the overall design problem in building reliable Internet connectivity was covered. This module examined specific attributes of BGP and how the attributes are applied individually and together address this design problem. The terminology, attributes, and details of this module are specific to BGP. However, the general concepts and problems raised are pertinent to routing architecture design, regardless of what specific protocols are being utilized.
