题目
Within an AS, all routers must run either BGP or IBGP.
An AS uses exterior gatew ay protocols (EGPs) to exchange information with other autonomous systems.
An AS is a group of routers under the same technical administration.
Within an AS, routes learned through BGP can be redistributed using interior gateway protocols.
Wi thin an AS, routes learned through an interior protocol cannot be redistributed using BGP to other autonomous systems.
