章節(jié)摘錄
Of course, in real life, few corporations the size of the one depicted in Figure 2-9 have theluxury of being designed "from the ground up" in such a c ordinated, logical fashion.Many, if not most, large internetworks have evolved from smaller internetworks that havebeen merged as divisions and corporations have merged. The result is that different networkadministrators have made different design choices for the various parts of the internetwork;when the parts are merged, the first order of business is basic interoperability.The second order of business might be the enforcement of routing policies. Some trafficfrom some domains of the internetwork to other domains may be required to always prefercertain links or routes, for example, or perhaps only certain routes should be advertisedbetween domains. In most cases, the necessary policies can still be implemented withredistribution between IGPs and tools such as route filters and route maps. You shouldimplement BGP only when a sound engineering reason compels you to do so, such as whenthe IGPs do not provide the tools necessary to implement the required routing policies orwhen the size of the routing tables cannot be controlled with summarization. BGP provesuseful, for instance, when many different IGPs are used in the domains. Here, BGP mightbe simpler to implement than attempting to redistribute among all the IGPs.When considering whether BGP is necessary in an intemetwork design, keep in mind whyexterior routing protocols were invented in the first place. Exterior routing protocols areused to route between autonomous systems——that is, between internetwork domains underdifferent administrative authorities. In a single corporate intemetwork, even a large onewith different domains under different local administrations, there is usually enough of acentralized authority to impose routing policy using the tools available with interior routingprotocols. When separate autonomous systems must interconnect, however, BGP might becalled for.
