多個VLAN向DHCP Server請求IP

實驗内容：

遠端DHCP Server分别為vlan10和20配置設定IP

實驗拓撲：

實驗分析：

1，三層交換機和DHCP Server要有分别去往各自的路由

2，要建立一個vlan和交換機直連的路由器通信，注意直連的實體接口要加入這個 vlan

實驗配置：

[Switch]vlan batch 10 20 

[Switch]dhcp enable 

[Switch]inter vlan 10

[Switch-Vlanif10]dhcp select relay 

[Switch-Vlanif10]dhcp relay server-ip 4.4.4.2

[Switch-Vlanif10]inter vlan 20

[Switch-Vlanif20]dhcp sel rel

[Switch-Vlanif20]dhcp relay server-ip 4.4.4.2

[Switch-Vlanif20]inter vlan 1

[Switch-Vlanif1]ip add 3.3.3.1 24

[Switch]inter g0/0/1

[Switch-GigabitEthernet0/0/1]port link-type access 

[Switch-GigabitEthernet0/0/1]port default vlan 10

[Switch-GigabitEthernet0/0/2]port link-type access 

[Switch-GigabitEthernet0/0/2]port default vlan 20

[Switch]ip route-static 4.4.4.0 24 3.3.3.2

[Route2]inter g0/0/0

[Route2-GigabitEthernet0/0/0]ip add 3.3.3.2 24

[Route2-GigabitEthernet0/0/0]inter g0/0/1

[Route2-GigabitEthernet0/0/1]ip add 4.4.4.1 24

[Route2]ip route-static 1.1.1.0 24 3.3.3.1

[Route2]ip route-static 2.2.2.0 24 3.3.3.1

[DHCP Server]dhcp enable

[DHCP Server]inter g0/0/0

[DHCP Server-GigabitEthernet0/0/0]dhcp select global 

[DHCP Server]ip pool vlan10

[DHCP Server-ip-pool-vlan10]network 1.1.1.0 mask 24

[DHCP Server-ip-pool-vlan10]gateway-list 1.1.1.1

[DHCP Server-ip-pool-vlan10]lease day 1

[DHCP Server]ip pool vlan20

[DHCP Server-ip-pool-vlan20]network 2.2.2.0 mask 24

[DHCP Server-ip-pool-vlan20]gateway-list 2.2.2.1

[DHCP Server-GigabitEthernet0/0/0]ip add 4.4.4.2 24

[DHCP Server]ip route-static 3.3.3.0 24 4.4.4.1

[DHCP Server]ip route-static 1.1.1.0 24 4.4.4.1

[DHCP Server]ip route-static 2.2.2.0 24 4.4.4.1
