When an IP packet is received via the Ethernet LAN and the destination IP address matches
one of the multicast IP address in the list, it is forwarded over the RF network. Remote
units will then send it over the remote LAN to the appropriate device(s).
IP OPTIMIZATION
IP Optimization is only available in Router Mode.
 Router Mode - RF ACK
RF Acknowledgements - Default = Disabled.
If RF ACK is enabled, the receiving ViPR will reply with a quick acknowledgement message
to the sending ViPR to indicate that it has received the packet successfully. If the sending
ViPR does not receive the acknowledgement, it will assume the message was lost and will
try to resend the message. The number of retries can be specified.
 Router Mode - OIP Retries
Number of OIP retries - Default = 2.
This parameter specifies the number of retries that the OIP layer will attempt if an
acknowledgement message is not received from the destination ViPR. Retries are only
enabled if Router mode is selected and RF ACK is turned on. The number of retries should
be increased if a there is a marginal RF path to another unit.
