Configuring DHCP IP Helper Address

A DHCP client is an internet host using DHCP to obtain configuration parameters such as an IP address, A DHCP relay agent is any host that forwards DHCP packets between clients and servers, Relay agents are used to forward requests and replies between clients and servers when they are not on the same subnet.
In this topology diagram, we will configure Router1 as the DHCP server for Vlan 30,40,60. I will configure 3 address pools one for each VLAN with the network of 172.16.30.0/24, 172.16.40.0/24 and 172.16.60.0/24.
My endpoint connected on Switch and configured Vlan 30,40,60 and assigned int with vlan and created a SVI for each vlan.
