address ranges are invalid
0.0.0.0 to 0.255.255.255
•
127.0.0.0 to 127.255.255.255

Destination Addr. – The IP interface that receives UDP frame relays. If this field
is 0.0.0.0, UDP packets are discarded. If this field is 255.255.255.255, UDP
packets are flooded to all IP interfaces.
An example of UDP Relay table use: To relay all UDP packets to interface 7.7.7.7
