拓扑图和具体要求如下

一、首先完成IP地址的划分和配置

R1配置如下

[r1]int LoopBack 0
[r1-LoopBack0]ip address 192.168.1.33 28
[r1]int LoopBack 1
[r1-LoopBack1]ip address 192.168.1.49 28
[r1-GigabitEthernet0/0/0]ip address 192.168.1.1 30
[r1-GigabitEthernet0/0/1]ip add 192.168.1.5 30

如上完成所有IP配置

完成R3的DHCP服务

[r3]dhcp enable 
r3]ip pool 1
[r3-ip-pool-1]network 192.168.1.96 mask 27
[r3-ip-pool-1]gateway-list  192.168.1.97
[r3-GigabitEthernet0/0/2]dhcp select global

PC1、PC2自动获取IP地址

PC>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fe77:173e
IPv6 address......................: :: / 128
IPv6 gateway......................: ::
IPv4 address......................: 192.168.1.126
Subnet mask.......................: 255.255.255.224
Gateway...........................: 192.168.1.97
Physical address..................: 54-89-98-77-17-3E
DNS server........................:

二、写缺省，加路由

缺省

[r1]ip route-static 0.0.0.0 192.168.1.2
[r1]ip route-static 0.0.0.0 192.168.1.6
[r3]ip route-static 0.0.0.0 192.168.1.14
[r2]ip route-static 0.0.0.0 192.168.1.10
[r4\]ip route-static 0.0.0.0 192.168.1.22

路由

[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

[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 192.168.1.96 27  192.168.1.1
[r2]ip route-static 192.168.1.96 27  192.168.1.10

[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 192.168.1.64 27  192.168.1.5
[r3]ip route-static 192.168.1.64 27  192.168.1.14

[r4]ip route-static 192.168.1.64 27  192.168.1.9
[r4]ip route-static 192.168.1.0 30  192.168.1.9
[r4]ip route-static 192.168.1.32 27  192.168.1.9
[r4]ip route-static 192.168.1.96 27  192.168.1.13
[r4]ip route-static 192.168.1.4 30  192.168.1.13
[r4]ip route-static 192.168.1.32 27  192.168.1.13

[r5]ip route-static 192.168.1.32 27  192.168.1.21
[r5]ip route-static 192.168.1.0 30  192.168.1.21
[r5]ip route-static 192.168.1.4 30  192.168.1.21
[r5]ip route-static 192.168.1.64 27  192.168.1.21
[r5]ip route-static 192.168.1.96 27  192.168.1.21

[r5]ip route-static 192.168.1.12 30  192.168.1.21
[r5]ip route-static 192.168.1.128 27  192.168.1.21

避免环路（空接口）

[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

条件6

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

条件7（端口映射）

[r1]aaa
[r1-aaa]local-user xiaopang privilege level 15 password cipher 123456
[r1-aaa]local-user xioapang service-type telnet 
[r1]user-interface vty 0 4
[r1-ui-vty0-4]authentication-mode aaa

[r5-GigabitEthernet0/0/1]nat static protocol  tcp global current-interface 23 in
side 192.168.1.33 23

条件8
