eNSP静态路由综合实验
实验要求：
分析：
1.首先进行子网划分
2.创建环回接口，分配划分好的子网
3.用缺省路由完成要求三
4.用浮动静态路由完成要求五
实验步骤：
先来子网划分，如图所示
配置IP
配置静态路由：
R1:
[R1]ip route-static 192.168.1.64 27 192.168.1.2
[R1]ip route-static 192.168.1.8 30 192.168.1.2
[R1]ip route-static 192.168.1.96 27 192.168.1.6
[R1]ip route-static 192.168.1.12 30 192.168.1.6
[R1]ip route-static 192.168.1.128 27 192.168.1.2
[R1]ip route-static 192.168.1.128 27 192.168.1.6
[R1]ip route-static 192.168.1.16 30 192.168.1.6

[R2]ip route-static 192.168.1.4 30 192.168.1.1
[R2]ip route-static 192.168.1.128 27 192.168.1.10
[R2]ip route-static 192.168.1.12 30 192.168.1.10
[R2]ip route-static 192.168.1.16 30 192.168.1.10
[R2]ip route-static 192.168.1.96 27 192.168.1.10
[R2]ip route-static 192.168.1.96 27 192.168.1.1
R3:
[R3]ip route-static 192.168.1.32 27 192.168.1.5
[R3]ip route-static 192.168.1.0 30 192.168.1.5
[R3]ip route-static 192.168.1.128 27 192.168.1.14
[R3]ip route-static 192.168.1.8 30 192.168.1.14
[R3]ip route-static 192.168.1.16 30 192.168.1.14
[R3]ip route-static 192.168.1.64 27 192.168.1.5
[R3]ip route-static 192.168.1.64 27 192.168.1.14
R4:
[R4]ip route-static 192.168.1.64 27 192.168.1.9
[R4]ip route-static 192.168.1.96 27 192.168.1.13
[R4]ip route-static 192.168.1.0 30 192.168.1.9
[R4]ip route-static 192.168.1.4 30 192.168.1.13
[R4]ip route-static 192.168.1.32 27 192.168.1.9
[R4]ip route-static 192.168.1.32 27 192.168.1.13
R5:
[R5]ip route-static 192.168.1.32 27 192.168.1.17
[R5]ip route-static 192.168.1.64 27 192.168.1.17
[R5]ip route-static 192.168.1.96 27 192.168.1.17
[R5]ip route-static 192.168.1.128 27 192.168.1.1
[R5]ip route-static 192.168.1.0 30 192.168.1.17
[R5]ip route-static 192.168.1.4 30 192.168.1.17
[R5]ip route-static 192.168.1.8 30 192.168.1.17
[R5]ip route-static 192.168.1.12 30 192.168.1.17
配置缺省路由：
[R1]ip route-static 0.0.0.0 0 192.168.1.2
[R1]ip route-static 0.0.0.0 0 192.168.1.6
[R2]ip route-static 0.0.0.0 0 192.168.1.10
[R3]ip route-static 0.0.0.0 0 192.168.1.14
[R4]ip route-static 0.0.0.0 0 192.168.1.18
环路问题的解决方法就是在黑洞路由器上配置一条指向汇总网段的空接口路由：
[R1]ip route-static 192.168.1.32 27 null 0
[R2]ip route-static 192.168.1.64 27 null 0
[R3]ip route-static 192.168.1.96 27 null 0
[R4]ip route-static 192.168.1.128 27 null 0
R5和R4正常通信走1000M链路，故障时用100M，实现如下：
先对R4向R5的通信方式做一个备份
[R4]ip route-static 0.0.0.0 0 192.168.1.22 preference 61
再对R5向R4的通信做备份
[R5]ip route-static 192.168.1.32 27 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.64 27 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.96 27 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.128 27 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.0 30 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.4 30 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.8 30 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.12 30 192.168.1.21 preference 61
当我们把1000M的那条路关掉后：
