第四步:给R3配置DHCP服务
[R1]dhcp enable 启动DHCP服务
[R3]ip pool aaa (池塘名字例如aaa) 创建名为aaa的DHCP池塘,
[R3-ip-pool-aaa]network 192.168.1.96 mask 27 绑定接口,可分配地址范围
[R3-ip-pool-aaa]gateway-list 192.168.1.97 下发网关
[R3-ip-pool-aaa]dns-list 114.114.114.114 8.8.8.8 下发DNS服务器信息
[R3-GigabitEthernet2/0/0]dhcp select global 对应接口激活全局池塘的配置
检测:
第五步:在R5上配置NAT
[R5]acl 2000
[R5-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255允许 感兴趣的网段
[R5-acl-basic-2000]int g 0/0/1
[R5-GigabitEthernet0/0/1]nat outbound 2000 接口调用NAT
第六步:完成空接口防环
[R1]ip route-static 192.168.1.32 27 NULL 0
[R2]ip route-static 192.168.1.64 27 NULL 0
[R3]ip route-static 192.168.1.64 27 NULL 0
[R4]ip route-static 192.168.1.128 27 NULL 0
第七步:完成远程登陆协议
[R1]telnet server enable 开启远程登录服务
Error: TELNET server has been enabled
[R1]aaa
[R1-aaa]local-user huawei password cipher 123456 privilege level 15
[R1-aaa]local-user huawei service-type telnet
[R1-aaa]q
[R1-ui-vty0-4]authentication-mode aaa
[R1-ui-vty0-4]quit
开启端口映射:
[R5]int g0/0/1
[R5-GigabitEthernet0/0/1]nat server protocol tcp global current-interface 23 ins
ide 192.168.1.1 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
第八步:浮动路由

ip route-static 192.168.1.128 255.255.255.224 192.168.1.21 preference 61
目的完成千兆百兆路径选择!
扩展:查看从该设备到设有该IP的设备的跳数。
