动态路由协议RIP和OSPF的综合应用 路由重分布技术 DHCP RIP OSPF 交换机端口聚合技术 Cisco

网络互连要求： 规划和设计各路由接口的IP地址； 除了路由器R4的G0/1、G0/2两个接口外，在其它路由器的所有接口上使用OSPF动态路由协议进行子网互连，进程号假设都为5021； 在路由器R4的G0/1、G0/2两个接口，及三层交换机的所有网段上启用RIP version2动态路由协议，且不要自动汇总； 在S1 、S2的接口F0/2、F0/3上，设置交换机端口聚合，聚合后的接口port1设置为trunk模式； 在S1 、S2上创建VLAN 2和VLAN 3，并在S1上设置这两个VLAN的地址分别为192.168.5.254/24、192.168.6.254/24; 在S2上设置这两个VLAN的地址分别为192.168.5.253/24、192.168.6.253/24； 在S1上为VLAN 2和VLAN 3的计算机创建DHCP服务，实现IP地址自动分配服务； 在路由器R4上使用路由重分布技术，使RIP和OSPF子网互相学习到，到彼此子网的的路由信息； 网络拓扑图：
