Configuring the Subscriber Module

• RIPv2 is enabled by default when routing mode is selected.
• You may turn RIP off by clearing the Enable RIP Interface check box for the Ethernet or the wireless interface. Any
RIP advertisements that are received on the designated interface are ignored. All other options on the page are
dimmed.
• If the Enable RIP Interface check box is selected, the unit sends RIP requests and “listens” for RIP updates coming
from RIP-enabled devices advertising on the network. You may configure the Receive field for RIPv1, RIPv2, or a
combination of both. Although the unit receives and processes these updates, it does not further propagate these
updates unless configured to advertise RIP. Again, you may configure the Advertize field for RIPv1, RIPv2, or a
combination of both.
• The ability to enable or disable default route propagation is not user configurable. Once initialized, the Subscriber unit
uses its static default route and does not advertise this route in RIP updates. If another router on your network is
configured to advertise its default route, this route overwrites the static default route configured on the Subscriber unit.
The Subscriber unit then also propagates the new dynamic default route throughout the network.
Be aware that, once a dynamic default route is learned, it behaves just as any other dynamic route learned through RIP.
This means if the device sending the default route stops sending RIP updates, the default route times out and the unit
has no default route to the network. Workarounds for this condition include rebooting or re-entering a static default route.
In general, the best approach is to disable the propagation of default routes on the other routers in your network unless
you understand the risks.
The following table describes the properties and features of each version of RIP supported.
RIP Example
In the following example, assume that both the BSU and the SUs all are configured in Routing mode with RIP enabled to
send and receive on both the Ethernet and Wireless interfaces. The network converges through updates until each unit
has the following routing table:
RIPv1 RIPv2 RIPv1 Compatible
Broadcast Multicast Broadcast
No Authentication Authentication Authentication
Class routing Classless routing (VLSM) Classless routing (VLSM)
Distance-vector protocol Distance-vector protocol Distance-vector protocol
Metric-Hops Metric-Hops Metric-Hops
Maximum Distance 15 Maximum Distance 15 Maximum Distance 15
