Routing Options
As a router, SpeedNet Radios provide a wireless connection between two or more separate
Ethernet subnets. Data is then routed between the Ethernet subnets. Route information can be
entered manually, or can be processed automatically by AODV, the SpeedNet Radio algorithm.
The type of network you are designing will help determine the best routing mode to use. If
the network consists of stationary SpeedNet Radios that are communicating either point-to-point
or point-to-multipoint, choose "Off”' for Ad Hoc Routing mode. This allows you to insert static
routes for each SpeedNet Radio and its connected network. If routes are not required to change
dynamically, "Off” is likely the best Ad Hoc Routing mode to choose. See Figure 3.
If the network consists of meshed SpeedNet Radios, choose "AODV," the Ad Hoc Routing
mode. This mode allows the SpeedNet Radios to automatically find their neighbors and update the
route tables to reflect this. AODV allows SpeedNet Radios to quickly and dynamically update the
route tables as the network topology changes. For environments where routes are required to
change dynamically, AODV is typically the best Ad Hoc Routing mode to choose.
Using Static Routes
Figure 3 is an example of a point-to-point SpeedNet Radio network. In this example, Subnet 1 has
been assigned the 192.168.1.0 Class C subnet, while Subnet 2 has been assigned the 192.168.2.0
Class C subnet. For the wireless network the 192.168.3.0 Class C subnet has been assigned.
In order to route traffic between subnets, several things must happen. First, it is
recommended that all hosts on a given subnet use the attached SpeedNet Radio as their default
gateway.
As
an alternative, manual routes can be entered in each host's routing table. Hosts from
Subnet 1 will list 192.168.1.1 as their default gateway. It is also necessary to add static routes in
each SpeedNet Radio. The SpeedNet Radio from Subnet 1 must have a static route to Subnet 2,
using the SpeedNet Radio from Subnet 2 as the gateway. The route should be set up like this:
192.168.2.0 255.255.255.0 192.168.3.2
