**3. BGP (Border Gateway Protocol)** Consider the network below in which: - Network W is a customer of ISP A. - Network Y is a customer of ISP B. - Network X is a customer of both ISPs A and C. **Diagram:** The diagram showcases a network topology with the following relationships: - Network W is connected to Network A. - Network A is interconnected with Networks B and C. - Network X is connected to Networks A and C. - Network Y is connected to Network B. ![Network Topology Diagram](URL-to-Diagram) *(Note: Actual image URL should be provided)* **Questions and Answers:** **a. What BGP routes will A advertise to X?** - A will advertise routes to its customer W as well as the routes to its peer or provider if applicable. In this case, it is likely to advertise the route to W. **b. What routes will X advertise to A?** - X will advertise to A the routes learned from its provider C. Additionally, X may also propagate any routes it knows from C. **c. What routes will A advertise to C? For each answer provide a one-sentence explanation.** - A will advertise routes to its customer W, as ISPs typically advertise their customer's routes to other peers and providers to ensure efficient routing and connectivity. This setup typically illustrates the customer-provider relationships in a BGP network environment and the resultant route advertisements among connected networks.
