option is left unchanged and directly relayed to the DHCP server.

Global configuration
The device may receive a DHCP request packet that already has the relay
option. This packet represents a packet that is relayed by a relay agent and
already has the option inserted. The gateway address in the received DHCP
packet should not be zero since it represents the IP address of the predecessor
DHCP relay agent.
This example shows how to set the policy to drop the DHCP request packet that
is relayed by other DHCP relay agent and already has option-82 inserted.
Verify the settings by entering the show ip dhcp relay command.
