📖 What is DHCP Relay Agent?

A router or host that listens for client DHCP broadcast messages and forwards them as unicast messages to a remote DHCP server.

🥋 Sensei Says:

"In Cisco IOS, a DHCP Relay Agent is configured on the router interface facing the client using the 'ip helper-address <server-IP>' command. It is essential when the DHCP server is not on the same subnet as the clients."
