Aprisa SR+ Product Description 1.5.0
The Radio Network as a Router
The Aprisa SR+ point-to-multipoint radio network can be considered as a router where the ‘network
Ethernet interface’ on each radio in the network is the ‘router port’.
The routing table for all directly attached devices to the Aprisa SR+ network, at the Base or the Remote
stations is automatically built and no static routes are required to be entered for those device routes.
The ‘Radio interface IP address’ is used internally for the radio network and automatic routes. It is not
used when setting static routes or default gateways.
Static route IP addresses or the default gateway should use the ‘network Ethernet interface’ IP address.
External network routers should be set with a high metric for the SR+ path, to prevent route updates
being sent over the radio network.
The Radio Network as a Router – Example
The purpose of this example is to determine the static route setting for router R2 in the base station and
remote station in the following network.
Since the Aprisa SR+ network should be considered as a router where the network Ethernet interface is the
‘router port’, the network configuration for setting the static routes or the default gateway IP addresses is
described in the follow figure:
Thus, the static route setting for router R2 at the Aprisa SR+ base station and remote station will be:
Destination Address
Destination Mask
Gateway Address
Static Route Setting at ?
192.168.3.0
255.255.255.0
192.168.2.1
Base station
192.168.3.0
255.255.255.0
192.168.2.2
Remote station
Note: The radio network (base station and remote stations) will automatically build routes to the attached
device e.g. SCADA Master station or attached router e.g. router R1 so static routes are not required for
these devices.
