Single DHCP server for multiple VLANs

During lunch, a friend of mine ask me about how does one go about setting up 1 DHCP server to serve multiple VLANs.

Generally the step listed below, involves router-on-a-stick method

1. Create VLANs on the router
2. Assign IP addresses to the each VLAN on the router.
3. Configure the router port connected to the switch as a VLAN trunk port.
4. Define routes to each network.
5. Configure the router to relay DHCP requests.
6. Create the VLANs on the switch.
7. Configure the switch port connected to the router as a VLAN trunk.
8. Add switch access ports to the appropriate VLANs.
