message. The relay agent, however, will forward only one DHCP_OFFER message of the
responses from the servers to the DHCP client. The DHCP client will try to respond to the
server which sent the DHCP_OFFER with DHCP_REQUEST message, but the relay
agent broadcasts it to all the DHCP servers again.
To prevent the unnecessary broadcast like this, you can configure a DHCP relay agent to
aware the server ID. This will allow the DHCP relay agent to forward DHCP_REQUEST
message to only one DHCP server with the unicast form under the multiple server
environment.
To enable/disable a DHCP relay agent to recognize the DHCP server ID option in the
forwarded DHCP_REQUEST message, use the following command.
