Hi!
You use the internal DHCP server.
Here is a sample:
ip dhcp excluded-address 10.200.3.1
!
ip dhcp pool pool1
network 10.200.3.0 255.255.255.0
default-router 10.200.3.1
dns-server
The default-router points to the VLANs ip address and that should take care of that specific VLAN where the subnet is located.
