If a device has a dhcp pool defined:
ip dhcp pool DATA network 192.0.2.0 255.255.255.0 default-router 192.0.2.1 domain-name test.net
But it also has a DHCP helper setup on the interface:
interface GigabitEthernet0/1 ip address 192.0.2.1 255.255.255.0 ip helper-address 198.51.100.10
Then what is the result? Is the DHCP addresses given from the helper? or from the local pool?
