By default, with the Option 82 support function enabled on the DHCP relay agent, the DHCP relay agent
will adopt the replace strategy to process the request packets containing Option 82. However, if other
strategies are configured before, then enabling the 82 supporting on the DHCP relay will not change the
configured strategies.
