实验拓扑：
实验目标：
通过综合实验复习路由部分的配置
实验步骤：
1：配置相关地址，确保直连网络的通信
2：配置所有Serial接口时钟频率为64000，参考带宽为1544K
3：配置EIGRP区域，AS号为100，并关闭自动汇总
4：对R4的loopback 接口实施手工汇总
5：在R1 上实施EIGRP 非等价负载均衡
6：根据拓扑所示，配置OSPF 多区域
7：在R6、R7 之间配置OSPF MD5 验证
8：确保R5成为DR
9：在R4 上配置静态默认路由，并配置EIGRP默认路由
10：在R5上配置静态默认路由，并配置OSPF默认路由
11：在R2、R3上实施HSRP，确保R2 成为主路由器，虚拟地址为192.168.1.254,并对R2的FA0/0
接口进行跟踪
12：保证EIGRP和OSPF两个区域通信，但不允许使用路由重分发
实验配置：
1：配置相关地址，测试直连网络的通信（略）
2：查看Serial接口默认时钟频率并按要求配置时钟频率
