静态路由综合实验

一、划分网段

6条骨干链路，每条骨干链路只需2个IP，所以用30位掩码

二、相应的ip配置

R1

R2

R3
R4

R5

R6

三、配置dhcp

[R3]dhcp enable
Info: The operation may take a few seconds. Please wait for a moment.done.
[R3]ip pool a
Info: It’s successful to create an IP address pool.
[R3-ip-pool-a]network 192.168.1.96 mask 27
[R3-ip-pool-a]gateway-list 192.168.1.97
[R3-ip-pool-a]dns-list 114.114.114.114 8.8.8.8
[R3]interface g0/0/2
[R3-GigabitEthernet0/0/2]dhcp select global

四、配置

R1

ip route-static 0.0.0.0 0.0.0.0 192.168.1.2

R4

由于路由表进行递归查找导致这个问题，在递归查找时会查找到从192.168.1.0 24 NULL0这个空接口查找。
解决方法：
把原来的缺省路由删掉，改用带接口的缺省路由命令
ip route-static 0.0.0.0 0 GigabitEthernet 0/0/3 192.168.1.18
ip route-static 0.0.0.0 0.0.0.0 192.168.1.22 preference 70

ip route-static 192.168.1.0 255.255.255.252 192.168.1.5
ip route-static 192.168.1.8 255.255.255.252 192.168.1.13

ip route-static 192.168.1.32 255.255.255.224 192.168.1.5
ip route-static 192.168.1.32 255.255.255.224 192.168.1.13
ip route-static 192.168.1.64 255.255.255.224 192.168.1.5
ip route-static 192.168.1.96 255.255.255.224 192.168.1.13
ip route-static 192.168.1.160 255.255.255.224 192.168.1.18
ip route-static 192.168.1.160 255.255.255.224 192.168.1.22 preference 70
ip route-static 192.168.1.128 255.255.255.224 NULL0
ip route-static 192.168.1.0 255.255.255.0 NULL0

R5

ip route-static 0.0.0.0 0.0.0.0 12.0.0.2
ip route-static 192.168.1.0 255.255.255.0 192.168.1.17
ip route-static 192.168.1.0 255.255.255.0 192.168.1.21 preference 70

五、nat配置，r1-r5可访问r6

[r5]acl 2000
[r5-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[r5-acl-basic-2000]int g0/0/1
[r5-GigabitEthernet0/0/1]nat outbound 2000

六、R6 telnet R5的公有IP 实际登录到R1上（进行端口映射配置）

[r5]int g0/0/1
[r5-GigabitEthernet0/0/1]nat server protocol tcp global current-interface 23 inside 192.168.1.1 23
