Read section 5.3.2, "Interdomain Routing," on pages 175-194. As you read, consider the following questions: What are the objectives of interdomain routing? What is the difference between transit and stub domains? What are some of the relationships you can expect to find in an interdomain routing policy?

Describe the BGP. How does BGP differ from the intradomain protocols RIP and OSPF that you've studied? What messages might the BGP generate? What is router convergence? Why is router convergence necessary? How is router convergence handled by the BGP?
