If the average packet size is 1000 bytes, the overhead saved is 1.5%; With a frame size of 64 bytes, the overhead saved
is 20%; and for frame sizes of 128 bytes, the saving is 10%. Network researches claim that most network traffic consists
of frames smaller than 100 bytes.
In order to support routers behind the SUs with multiple subnets and prevent routing loops, you want individual routes
(and more then one) per SU.
Routing Mode Examples
In the first example, both the BSU and the SUs are configured for Routing mode. This example is appropriate for
businesses connecting remote offices that have different networks.
In example 2, the BSU is in Routing mode and the SUs are in Bridge mode. Notice the PCs behind the SUs must
configure their default gateways to point to the BSU, not the SU.
Notes:
• One of the most important details to pay attention to in Routing mode are the unit’s and the PC’s default gateways. It
is a common mistake to set up the PC’s gateway to point to the SU when the SU is in Bridge mode and the BSU is in
Routing mode. Always check to make sure the PCs on your network are configured to send their IP traffic to the
correct default gateway.
• Be sure to reboot the unit to permanently save static routes. New routes take effect immediately without a reboot, but
are not permanently saved with your configuration until you do reboot the device. An unexpected power outage could
cause static routes you entered to “disappear” when the unit reboots if they have not been saved. You also should
save a copy of your unit’s configuration file in case the unit must be reloaded. This saves you from being required to
re-enter numerous static routes in a large network.
• The routing table supports up to 500 static routes.
