Method for configuring DHCP server using DHCP option 82

摘要

The method involves sending Dynamic host configuration protocol (DHCP)messages over Media access control (MAC)multicast to a MAC multicast address by a network device in addition to the regular DHCP discovers over MAC Broadcast. The MAC multicast clear information from a MAC multicast address is sent to the DHCP server through the DHCP relay agents. The associated network device filters out the multicast. The assignment for the network device for allocated Internet protocol (IP)address is determined based on the topology information.
