So here’s Router 1 sh ip int brief shows us the IP addresses configured on the router.

Here’s the loopback interface, here’s the IP address on gigabit is 0/0/0

So the first thing we need to do is configure an exclusion range

So ip dhcp excluded-address to

The next thing we need to do is configure a DHCP pool called PC. The network to use is with a subnet mask of /24 with I need to configure a default router or default gateway of because that’s the IP address of Router 1. So the default route will be that. DNS server will be the router and that looks good.

So show run there is our exclusion range and there’s our DHCP poll show ip dhcp binding. Our plant has already been allocated an IP address so let’s confirm that by opening up a command prompt. IP config, there’s the IP address of the PC, there’s the subnet mask, there’s the default gateway.

Can the PC ping Router1? Yes it can. Can it ping the loopback of Router 1? Yes it can.

And to confirm that, sh ip int brief there’s the loopback of Router 1 and the PC can ping the loopback of Router 1.

Can the router ping the PC? Yes it can. We’ve successfully configured a DHCP on Router 1 and tested that the PC gets an IP address via DHCP and that the PC can ping the loopback of Router 1.

That was a very basic DHCP lab. In the next lab, it gets more complicated.
