DHCP的综合实验
需求
- PC1、2、3、4，自动获得IP地址
- 且各个主机之间能互相通信
拓扑图
配置思路
- 配置DHCP客户端
- 配置DHCP服务器
- 配置DHCP中继
- 配置DHCP客户端和中继之间的交换网络
- 配置DHCP中继和服务器之间的路由网络
配置命令
- AR ——DHCP服务器
@PC1设置为DHCP客户端 @设置DHCP服务器 undo terminal monitor system-view sysname DHCP dhcp enable ip pool VLAN10 network 192.168.10.0 mask 24 gateway-list 192.168.10.254 dns-list 8.8.8.8 lease day 10 excluded-ip-address 192.168.10.253 quit ip pool VLAN20 network 192.168.20.0 mask 24 gateway-list 192.168.20.254 dns-list 8.8.8.8 lease day 20 excluded-ip-address 192.168.20.253 quit interface gi0/0/0 ip address 192.168.66.1 24 dhcp select global quit ip route-static 0.0.0.0 0 192.168.66.254
注意： 默认路由不能丢，很多人都配置完成，却忘记了默认路由，主机始终获取不到IP地址
- lsw1
lsw1： undo terminal monitor system-view sysname lsw1 vlan batch 10 20 66 dhcp enable interface vlanif 10 ip address 192.168.10.254 24 dhcp select relay dhcp relay server-ip 192.168.66.1 quit interface vlanif 20 ip address 192.168.20.254 24 dhcp select relay dhcp relay server-ip 192.168.66.1 quit interface vlanif 66 ip address 192.168.66.254 24
lsw2
undo terminal monitor system-view sysname lsw2 vlan batch 10 20 66 quit interface Ethernet0/0/1 port link-type access port default vlan 10 quit interface Ethernet0/0/2 port link-type access port default vlan 10 quit interface GigabitEthernet0/0/1 port link-type trunk port trunk allow-pass vlan 2 to 4094 quit
lsw3
undo terminal monitor system-view sysname lsw3 vlan batch 10 20 66 interface Ethernet0/0/1 port link-type access port default vlan 20 quit interface Ethernet0/0/2 port link-type access port default vlan 20 quit interface GigabitEthernet0/0/2 port link-type trunk port trunk allow-pass vlan 2 to 4094 quit
