interface is used to populate the gi_addr field of all DHCP messages originating from either CMs or Hosts (CPEs)
Policy—When the DHCP Relay Agent is defined for Policy operation on a specific interface, the Primary IP address of the interface is
used to populate the gi_addr field of all DHCP messages originating from CMs. For Hosts (CPEs), a designated secondary IP address

round-robin selection, choosing the next entry in the list with each new DHCP transaction.
