case the primary address does not respond to the request.
IP/UDP Relay
The Express L128/L128T can be configured as a relay agent for UDP broadcast
packets. Normally, a router will not forward UDP broadcast packets. How-
ever, many network applications use UDP broadcasts to configure addresses,
host names, and other information. If hosts using these protocols are not on the
same network segment as the servers providing the information, the client
programs will not receive a response without enabling the UDP relay agent.
