DHCP Relay agent

Adrian Ardelean

Hi,

I have a 2921 with 4 segments:

Let's say:

172.16.0.0/27 Gi0/1 (172.16.0.1)

172.16.2.0/23 Gi0/2 (172.16.2.1)

172.16.5.0/24 Gi0/3  (172.16.5.1)

172.16.10.0/26 Gi0/4 (172.16.10.1)

My DHCP server is 172.16.5.2 and I need to serve clients from 172.16.2.0/23 by MAC address and only to that segment.

I'm kind of very new with Cisco....

How can I do that?

Thank you!

Hi Adrian,

Go under interface gi0/2 and apply the config below:

ip helper-address 172.16.5.2.

This will relay all your dhcp request to that specified DHCP server. You will need to create a dhcp pool for that subnet on your DHCP server.

HTH.
