先放思维导图：
基本拓扑图：
AR2： system-view DHCP enable ip pool vlan10 network 192.168.10.0 mask 24 gateway-list 192.168.10.1 dns-list 114.114.114.114 8.8.8.8 lease day 7 hour 23 minute 59 ip pool vlan20 network 192.168.20.0 mask 24 gateway-list 192.168.20.1 dns-list 114.114.114.114 8.8.8.8 lease day 7 hour 23 minute 59 excluded-ip-address 192.168.20.250 192.168.20.254 int g0/0/0 ip address 10.10.10.1 30 ip route-static 192.168.10.0 255.255.255.0 10.10.10.2 ip route-static 192.168.20.0 255.255.255.0 10.10.10.2 int g0/0/0 dhcp select global LSW1： vlan batch 10 20 int e0/0/1 port link-type access port default vlan 10 int e0/0/2 port link-type access port default vlan 20 int g0/0/2 port link-type trunk port trunk allow-pass vlan 10 20 LSW2： vlan batch 10 20 100 int vlan 10 ip add 192.168.10.1 24 int vlan 20 ip add 192.168.20.1 24 Int vlan 100 ip add 10.10.10.5 30 int g0/0/2 port link-type trunk port trunk allow-pass vlan 10 20 int g0/0/1 port link-type access port deafult vlan 100 ip route-static 0.0.0.0 0.0.0.0 10.10.10.6 dhcp enable int vlan 10 dhcp select relay dhcp relay server-ip 10.10.10.1 int vlan 20 dhcp select relay dhcp relay server-ip 10.10.10.1 AR1： system-view int g0/0/1 ip address 10.10.10.2 30 int g0/0/0 ip address 10.10.10.6 30 ip route-static 0.0.0.0 0.0.0.0 10.10.10.1 ip route-static 192.168.10.0 255.255.255.0 10.10.10.5 ip route-static 192.168.20.0 255.255.255.0 10.10.10.5 dhcp enable所有命令刷入相应位置，即可获得自动dhcp，具体可看后面的补充实验，大致上差不多的
补充实验：
AR1： 1.接口ip地址配置 2.开始DHCP的功能 3.配置vlan 10 20的静态路由 system-view int g0/0/0 ip address 16.0.0.6 30 int g0/0/1 ip address 16.0.0.2 30 acl 2000 rule permit source 192.168.16.0 0.0.0.255 rule permit source 192.168.26.0 0.0.0.255 rule deny source any int g0/0/2 ip address 16.16.16.1 29 nat outbound 2000 dhcp enable ip route-static 192.168.16.0 255.255.255.0 16.0.0.5 ip route-static 192.168.26.0 255.255.255.0 16.0.0.5 ip route-static 0.0.0.0 0.0.0.0 16.16.16.6 LSW1： 1.创建2个vlan 2.将相应接口加入vlan 3.g0/0/1配置为trunk system-view vlan batch 10 20 int e0/0/1 port link-type access port default vlan 10 int e0/0/2 port link-type access port default vlan 20 int g0/0/2 port link-type trunk port trunk allow-pass vlan 10 20 AR2: system-view int g0/0/0 ip address 16.0.0.1 30 ip route-static 0.0.0.0 0.0.0.0 16.0.0.2 dhcp enable ip pool vlan_10 network 192.168.16.0 mask 24 gateway-list 192.168.16.1 dns-list 114.114.114.114 8.8.8.8 lease day 1 hour 1 minute 1 excluded-ip-address 192.168.16.250 192.168.16.254 ip pool vlan_20 network 192.168.26.0 mask 24 gateway-list 192.168.26.1 dns-list 114.114.114.114 8.8.8.8 lease day 1 hour 1 minute 1 excluded-ip-address 192.168.26.250 192.168.26.254 int g0/0/0 dhcp select global LSW2： 1.创建3个vlan 2.在vlan中配置ip地址 3.将接口加入相应的vlan 4.g0/0/1配置trunk 5.配置出去的默认路由 6.开DHCP功能 7.配置DHCP中继 system-view vlan batch 10 20 100 int vlan 10 ip address 192.168.16.1 24 int vlan 20 ip address 192.168.26.1 24 int vlan 100 ip address 16.0.0.5 30 int g0/0/2 port link-type trunk port trunk allow-pass vlan 10 20 int g0/0/1 port link-type access port default vlan 100 ip route-static 0.0.0.0 0.0.0.0 16.0.0.6 dhcp enable int vlan 10 dhcp select relay dhcp relay server-ip 16.0.0.1 int vlan 20 dhcp select relay dhcp relay server-ip 16.0.0.1对应位置刷入命令： 通过命令来获取自动分配的IP地址 测试连通性
同理，可得PC2也是一样的效果，就不再多赘述了。
但是云并没有ping通，因为在共享地址时，我并没有配置现有的ip——16.16.16.6 这里的ip就明显不合适，需要改为对应的IP，还需要重启电脑，为了简便，直接看结果吧，如果不懂怎么操作的，欢迎私聊！
