eNSP靜態路由綜合實驗

實驗要求：

分析：

1.首先進行子網劃分

2.創建環回介面，分配劃分好的子網

3.用預設路由完成要求三

4.用浮動靜態路由完成要求五

實驗步驟：

先來子網劃分，如圖所示

配置IP

配置靜態路由：

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
[R1]ip route-static 192.168.1.16 30 192.168.1.2

R2:

[R2]ip route-static 192.168.1.32 27 192.168.1.1
[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

配置預設路由：

[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

環路問題的解決方法就是在黑洞路由器上配置一條指向匯總網段的空介面路由：
[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鏈路，故障時用100M，實作如下：
先對R4向R5的通信方式做一個備份
[R4]ip route-static 0.0.0.0 0 192.168.1.22 preference 61
再對R5向R4的通信做備份
[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

當我們把1000M的那條路關掉后：
