实验拓扑

实验要求

1、R6为ISP，接口IP地址均为公有地址，该设备只能配置IP地址，之后不能再对其进行任何配置；
2、R1-R5为局域网，私有IP地址192.168.1.0/24，请合理分配；
3、R1、R2、R4，各有两个环回IP地址；R5,R6各有一个环回地址；所有路由器上环回均代表连接用户的接口；
4、R3下面的两台PC通过DHCP自动获取IP地址；
5、选路最佳，路由表尽量小，避免环路；
6、R1-R5均可以访问R6的环回；
7、R6 telnet R5的公有地址时，实际登录到R1上；
8、R4与R5正常通过1000M链路，故障时通过100m链路；

路由完成后ping的结果

这里是pingR5环回的结果



挨个ping都能通

3.配置DHCP

在R3配置DHCP

dhcp enable
#
ip pool 1gateway-list 192.168.1.97 network 192.168.1.96 mask 255.255.255.224 dns-list 8.8.8.8 interface GigabitEthernet0/0/0ip address 192.168.1.97 255.255.255.252 dhcp select global

获取情况

配置telnet

在R1上配置

[R1-aaa]local-user huawei password cipher 123456 privilege level 15 
[R1-aaa]local-user huawei service-type telnet 
[R1-ui-vty4]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode aaa

可以登陆,配置成功

配置nat

在R5上配置easy-ip

[R5]acl 2000
[R5-acl-basic-2000]rule permit 192.168.1.0 0.0.0.255
[R5-acl-basic-2000]int g0/0/1
[R5-GigabitEthernet0/0/1]nat outbound 2000

R1能够ping通1.0.0.1

其他都能ping通,就不放多余截图了

配置端口映射

nat server protocol tcp global current-interface telnet inside 192.168.1.1 telnet

可以登陆

浮动静态路由

关闭1000M链路接口

可以发现路由已经更换
