Appendix B. Answers to Configuration Exercises
Table 2-7 lists the autonomous systems, routers, interfaces, and addresses used in Exercises 1 through 4. All interfaces of the routers are shown; physical interfaces may be changed for your solutions to fit your available resources. For each exercise, if the table indicates that the router has a loopback interface, that interface should be the source of all IBGP connections. EBGP connections should always be between physical interface addresses, unless otherwise specified in an exercise. Neighbor descriptions will always be configured to be the router names.
