第5题：
A. Within an AS, all routers must run either BGP or IBGP.
B. An AS uses exterior gatew ay protocols (EGPs) to exchange information with other autonomous systems.
C. An AS is a group of routers under the same technical administration.
D. Within an AS, routes learned through BGP can be redistributed using interior gateway protocols.
E. Wi thin an AS, routes learned through an interior protocol cannot be redistributed using BGP to other autonomous systems.
第6题：
A. Only routers can split boundaries (horizons) between concentric networks.
B. Each AS must keep routing tables converged to prevent dead routes from being advertised across boundaries.
C. Networks can only remain fully converged if all information is sent out all active interfaces.
D. Information about a route should not be sent back in the direction from which the original update came.
E. Distance vector protocols need fall back routers that are responsible for momentary loops.
第7题：
A. The exchange of an advertisement is triggered by a change in the network.
B. All routers exchange routing tables with each other in a multipoint network.
