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
