Experimental environment:

Experimental purpose:

1. Divide the VLAN into vlan10\ vlan100\ vlan200 and specify IP as 192.168.10.254\ 192.168.100.254\ 192.168.200.254 respectively.

2. Divide fa0/1\ fa02\ fa04 into VLAN100\ VLAN 200\ VLAN10.

3. Enable the routing protocol in the layer 3 switch so that the VLAN can communicate with each other. (if only to obtain the IP address, not to use a routing protocol)

4. Enable ip helper-address for each VLAN on the layer 3 switch.

5. Add an IP address pool on the server.

6. Check whether PC can obtain the IP address normally.

1. Divide the VLAN into vlan10\ vlan100\ vlan200 and specify IP as 192.168.10.254\ 192.168.100.254\ 192.168.200.254 respectively.

3. Enable the routing protocol in the layer 3 switch so that the VLAN can communicate with each other.

Switch (config) # ip routing

4. Enable ip helper-address for each VLAN on the layer 3 switch.

Switch (config) # int vlan 10

Switch (config-if) # ip helper-address 192.168.10.1 (DHCP server IP)

Switch (config-if) # exit

Switch (config) # int vlan 100

Switch (config-if) # ip helper-address 192.168.10.1

Switch (config-if) # exit

Switch (config) # int vlan 200

Switch (config-if) # ip helper-address 192.168.10.1

Switch (config-if) # exit

5. Add an IP address pool on the server.

6. Check whether PC can obtain the IP address normally, as follows:
