项目三距离向量路由协议RIP和EIGRP项目内容任务一：如图3.1所示的网络拓扑，实现计算机A和B的数据传输。R1、R2与R3分别通过Serial端口相连。要求：（1） 采用路由协议RIPv2，使整个网络可以通信；（2） 将R2的S1/0设置成被动接口，查看路由器的路由表；图3.1 网络拓扑任务二：如图3.1所示的网络拓扑，实现计算机A和B的数据传输。R1、R2与R3分别通过Serial端口相连。要求：（1）采用路由协议EIGRP，使整个网络可以通信；（2）在图3.1中的R1与R2之间增加一条串行链路，查看等价链路的负载均衡；（3）在（2）的基础上，修改R1与R2之间的一条串行链路的带宽，查看非等价链路的负载均衡。（4）如图3.2所示，在R1设置4个环回口地址，然后在R1的S1/0接口进行汇总，观察R2、R3的路由表。图3.
