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
