Executive Summary

A network's routing policy is embodied in the configuration of the routing protocols of each individual router and link in the network. These configurations are the basis on which the Internet routing protocols creates the "network-wide intelligence" that transforms individual network components into an operational IP network. Initially the goal of a routing policy was to just ensure connectivity. But nowadays the requirements and therefore the complexity has grown substantially and includes maintaining contractual or business relationships between different domains, ensuring resilience requirements even under overload, achieving stability, guaranteeing efficient internal operations, and supporting growing customer demands to control their traffic flows.
