Usage guidelines
A DHCP client unicasts a DHCP-RELEASE message to the DHCP server to release its IP address.
The DHCP relay agent conveys the message to the DHCP server and does not remove the
IP-to-MAC entry of the client.
With this feature, the DHCP relay agent uses the IP address of a client and the MAC address of the
DHCP relay interface to periodically send a DHCP-REQUEST message to the DHCP server.
