静态综合实验

1.首先进行子网划分

基于192.168.1.0 24划分

一共7个路由器需要7个网段还有7个主干网

192.168.1.0/24 ----用于骨干

192.168.1.32/27 ----R1环回 192.168.1.32/28 192.168.1.48/28

192.168.1.64/27 --- R2环回 192.168.1.64/28 192.168.1.80/28

192.168.1.96 /27 ----R3环回192.168.1.96/28 192.168.1.112/28

192.168.1.128 /27 ----R4环回 192.168.1.128/28 192.168.1.144/28

192.168.1.160/27----R5环回 192.168.1.160/27

192.168.1.192 /27

192.168.1.224 /27

骨干网络划分：

由于骨干网络总共6个网段，需要把192.168.1.0/27划分为192.168.1.0/30等8个网段

192.168.1.0/27 借3位

192.168.1.0 /30

192.168.1.4 /30

192.168.1.8 /30

192.168.1.12 /30

192.168.1.16/30

192.168.1.20/30

192.168.1.24/30 

192.168.1.1.28/30

2.所有路由上环回

要实现r1-r5的环回可以访问r6的环回要是用nat技术实现公网和私有网络的连通

[r5]acl 2000
[r5-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255

[r5-acl-basic-2000]int g 0/0/2
[r5-GigabitEthernet0/0/2]nat outbound 2000

6.防止环路

[r1]ip route-static 192.168.1.32 27 NULL 0

[r2]ip route-static 192.168.1.64 27 NULL 0

[r4]ip route-static 192.168.1.128 27 NULL 0

7.实现

 首先在r1上开启telnet功能并且创建用户账号密码：

[r1]aaa
[r1-aaa]local-user yps privilege level 15 password  cipher 123456
Info: Add a new user.
[r1-aaa]local-user yps service-type telnet

[r1]user-interface vty 0 4
[r1-ui-vty0-4]authentication-mode aaa

然后在r5上做一个端口映射到r1的talnet

[r5-GigabitEthernet0/0/2]nat server protocol tcp global current-interface 23 ins
ide 192.168.1.33 23
Warning:The port 23 is well-known port. If you continue it may cause function fa
ilure.
Are you sure to continue?[Y/N]:y
