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、RIPv1
B、RIPv2
C、EIGRP
D、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。
