OSPF实验
实验拓扑图
实验要求：
R1的环回1代表生产区的主服务器，环回2代表办公区的主服务器
R2的环回1代表生产区的备份服务器，环回2代表办公区的备份服务器
R5的环回1代表生产区的电脑，环回2代表办公区的电脑
R3为生产区的路由器，R4为办公区的路由器
1、办公区的电脑直接到办公服务器，不通过生产区服务器；生产区的电脑相同
2、办公挂了，不切生产，直接走R6
3、生产挂了，走办公，如果办公也挂了，再走R6
方法
开辟子接口，R1与R2的e0/0，R1与R4的e0/2，R2与R3的e0/2，R3与R5的s1/0，R4与R5的s1/1之间开辟子接口，将一条链路虚拟成两条，一条属于生产区域，一条属于办公区域，并修改链路cost值，控制选路
结果
链路故障
办公断掉，直接走R6
生产断掉，走办公
生产断掉，办公也断掉，走R6
