Good day,
I have a windows domain controller that has the DHCP role installed. The DHCP role issues out IP addresses,. I would now like like the cisco router to issue out IP addresses to clients within my domain. What is the process of setting this up ?Routing, DHCP

You need to configure your router DHCP Server config :
ip dhcp excluded-address 10.10.10.1 10.10.10.20 ( iam excluding IP address 1-20 reservation)
!
ip dhcp pool MYPOOL
network 10.10.10.0 255.255.255.0
default-router 10.10.10.1
dns-server 8.8.8.8 - this can change to your local DNS if you have one
interface vlan X
ip address 10.10.10.1 255.255.255.0
no shutdow
On the client-side switches, configure IP helper-address to router IP

Hello,
on a side note, be careful if the Windows domain controller is in the same broadcast domain/subnet as the clients. The clients will get an IP address form whoever responds first. If your DC is in the same subnet, better disable the scope altogether...

Hello
Even though a router can perform dhcp service, It doesn’t mean it should, Windows servers are designated servers that are built to perform services like dhcp/dns/wins registration so I would suggest you stick with your windows server than use a rtr, especially as you mention you have domain controllers which suggests you have a large enough client based to have active directory running on your network.
