H3C配置三层交换DHCP服务

根据拓扑图建立物理连接

配置vlan 虚拟接口IP地址

[H3C]sysname R1
[R1]vlan 100
[R1-vlan100]vlan 200
[R1-vlan200]exit
[R1]int
[R1]interface GigabitEthernet 1/0/1
[R1-GigabitEthernet1/0/1]port link-type access
[R1-GigabitEthernet1/0/1]port access vlan 100
[R1-GigabitEthernet1/0/1]quit
[R1]interface GigabitEthernet 1/0/2
[R1-GigabitEthernet1/0/2]port link-type access
[R1-GigabitEthernet1/0/2]port access vlan 200
[R1-GigabitEthernet1/0/2]exit
[R1]interface Vlan 100
[R1-Vlan-interface100]ip address 192.168.100.1 24
[R1-Vlan-interface100]undo shutdown
[R1-GigabitEthernet1/0/2]exit
[R1]interface Vlan 200
[R1-Vlan-interface200]ip address 192.168.200.1 24
[R1-Vlan-interface200]undo shutdown

DHCP服务配置内容

(1)创建用于给vlan100和vlan200分配ip地址的地址池，并配置相应参数

vlan100分配ip地址的地址池

[R1]dhcp server  ip-pool  vlan100pool
[R1-dhcp-pool-vlan100pool]network 192.168.100.0 24
[R1-dhcp-pool-vlan100pool]gateway-list 192.168.0.1
[R1-dhcp-pool-vlan100pool]dns-list 123.88.8.2
[R1-dhcp-pool-vlan100pool]exit

vlan200分配ip地址的地址池

[R1]dhcp server ip-pool vlan200pool
[R1-dhcp-pool-vlan200pool]network 192.168.200.0 24
[R1-dhcp-pool-vlan200pool]gateway-list  192.168.200.1
[R1-dhcp-pool-vlan200pool]dns-list  123.88.8.8
[R1-dhcp-pool-vlan200pool]exit

(2）配置排除ip地址

dhcp server forbidden-ip 192.168.100.1 192.168.100.20
dhcp server forbidden-ip 192.168.200.1 192.168.200.20

(3）配置VLAN100虚接口、VLAN200虚接口工作在dhcp server模式并选择相应的地址池。

[R1]interface  Vlan 100
[R1-Vlan-interface100]dhcp  select server
[R1-Vlan-interface100]dhcp server apply  ip-pool vlan100pool
[R1-Vlan-interface100]exit
[R1]interface vlan 200
[R1-Vlan-interface200]dhcp select server
[R1-Vlan-interface200]dhcp server apply ip-pool vlan200pool
[R1-Vlan-interface200]exit

(4）启动dhcp服务
