问题 A routing protocol is required that supports: 1) routing update authentication 2) an addressing scheme that conserves IP addresses 3) multiple vendors 4) a network with over 50 routers Which routing protocol fulfills these requirements?

选项 A、RIPv1B、RIPv2C、EIGRPD、OSPF

答案D

解析首先RIPv1是不支持认证的,因此答案A我们可以排除。是支持多厂商的,因此是一个开放的标准的协议,可以排除EIGPR,因为这是个CISCO私有的协议。网络的大小可以超过50台路由器,那RIPv2就不满足了,因为RIP最大支持16跳。那么答案就是OSPF了。
