5.2 PRODUCT SETUP
• The route destination and mask must match. This can be verified by checking that
RtDestination and RtMask = RtDestination
Example of good configuration: RtDestination = 10.1.1.0; Rt Mask = 255.255.255.0
Example of bad configuration: RtDestination = 10.1.1.1; Rt Mask = 255.255.255.0
The following rules must be observed when you configure static routes:
• The route destination must not be a connected network
• The route gateway must be on a connected network. This rule applies to the gateway address of the default route as
well. This can be verified by checking that:
(RtGwy & Prt1Mask) == (Prt1IP & Prt1Mask) || (RtGwy & Prt2Mask) == (Prt2IP & Prt2Mask) || (RtGwy & Prt3Mask) ==
(Prt3IP & Prt3Mask)
where
& is the bitwise-AND operator
== is the equality operator
|| is the logical OR operator
ROUTING BEHAVIOR COMPARED TO PREVIOUS RELEASES
Prior to release 7.10, the UR did not have an explicit manner of configuring routes. The only available route was the default
route configured as part of the network settings (port gateway IP address). This limited the ability to route to specific desti-
nations, particularly if these destinations were reachable through a different interface than the one on which the default
gateway was.
Starting with UR 7.10, up to six static network routes can be configured in addition to a default route. The default route con-
figuration was also moved from the network settings into the routing section.

The figure shows an example of topology that benefits from the addition of static routes.
10.1.1.0/24
In the figure, the UR connects through the following two Ethernet ports:
• Port 1 (IP address 10.1.1.2) connects the UR to LAN 10.1.1.0/24 and to the Internet through Router1. Router 1 has an
interface on 10.1.1.0/24 and the IP address of this interface is 10.1.1.1.
• Port 2 (IP address 10.1.2.2) connects the UR to LAN 10.1.2.0/24 and to the EnerVista software through Router 2.
Router 2 has an interface on 10.1.2.0/24 and the IP address of this interface is 10.1.2.1.
The configuration before release 7.10 was as follows:
• PRT1 IP ADDRESS = 10.1.1.2
PRT1 SUBNET IP MASK = 255.255.255.0
PRT1 GWY IP ADDRESS = 10.1.1.1
