RipEX1-Base Configuration

Fig. 3.1: Centre configuration

In the Settings menu, change the Unit name to RipEX1-Base. The Operating mode is set to “Router” (“GRE” is not configurable in the Bridge mode).

Within the Radio parameters, “Flexible” mode is set. Configure the 10.10.10.1/255.255.255.0 IP address/netmask parameters. The frequency must be the same for all RipEX units, but otherwise is configurable as required. The channel spacing is set to 25 kHz and Modulation rate to 16DEQAM (83.33 kbps).

NOTE:
The parameters marked with a small red square must be the same within all RipEX units in network.

The last step is the Ethernet IP configuration – 192.168.131.238 / 255.255.255.0.

Fig. 3.2: Centre station GRE configuration

GRE configuration is very straight-forward (all parameters are described at the beginning of this chapter). The Peer address is set to RipEX2-Remote Ethernet address – 192.168.141.239. The tunnel address should not overlap with any other subnet in the network.

IMPORTANT:
The GRE tunnel only ever uses two IP addresses; thus the /31 mask is recommended.

Because the local GRE IP address was set as 10.2.2.0 the remote must be set to 10.2.2.1. The check box “Active” is enabled.

Fig. 3.3: Centre station routing rules

The last menu to configure is “Routing”. Together, 6 routes are configured in this example. You might configure different rules, but be consistent across all RipEX units.
