forward protocol + dhcp helper address

Hi all

ip helper-address <dhcp server ip> works fine if the dhcp server is
remote

however i m not sure ...why some examples show

ip forward-protocol udp + ip helper-address <dhcp server ip>

what is the difference i get if i include " ip forward-protocol udp
" along with " ip helper-address <dhcp server ip> "
