Hi

Configuring DHCP Server on a Router or Layer 3 Switch

Router(config)#ip dhcp pool internal	Creates a DHCP pool called internal.
Router(dhcp-config)#network 172.16.10.0 255.255.255.0	Defines the range of addresses to be leased.
Router(dhcp-config)#default-router 172.16.10.1	Defines the address of the default router for the client.
Router(dhcp-config)#dns-server 172.16.10.10	Defines the address of the Domain Name System (DNS) server for the client.

Hello,

this is pretty straightforward. Just create a DHCP pool for each (VLAN) interface. A sample file is attached...

ip routing
!
ip dhcp excluded-address 192.168.1.1
ip dhcp excluded-address 192.168.2.1
ip dhcp excluded-address 192.168.3.1
!
ip dhcp pool VLAN1
network 192.168.1.0 255.255.255.0
default-router 192.168.1.1
dns-server 8.8.8.8
!

ip dhcp pool VLAN2
network 192.168.2.0 255.255.255.0
default-router 192.168.2.1
dns-server 8.8.8.8

!
ip dhcp pool VLAN3
network 192.168.3.0 255.255.255.0
default-router 192.168.3.1
dns-server 8.8.8.8
!
interface Vlan1
ip address 192.168.1.1 255.255.255.0
!
interface Vlan2
mac-address 0090.21b5.b101
ip address 192.168.2.1 255.255.255.0
!
interface Vlan3
mac-address 0090.21b5.b102
ip address 192.168.3.1 255.255.255.0
