Usage guidelines

The smart relay feature allows the relay agent to use secondary IP addresses as the gateway address when the DHCP server does not reply the DHCP-OFFER message. The relay agent initially inserts its primary IP address in the giaddr field before forwarding a request to the DHCP server. If no DHCP-OFFER is returned after two retries, the relay agent switches to secondary IP addresses.

Without this feature, the relay agent always uses the primary IP address as the gateway address.
