-====DHCP Relay====
-Relays are configured with **''ip helper-address x.x.x.x''** to specify which address to forward received DHCP requests. When our RTR forwards a DHCP request out via Relay, it does so with the **''SOURCE ADDRESS''** of the ''**INTERFACE**'' the ''**HELPER-ADDRESS**'' command was configured on. When this happens, the DHCP server can look at the ''**SOURCE ADDR**'' of the packet, and know exactly which scope to lease an address from - the same network that source resides in, ofc.
