Note the following:
• There is no option to turn off receiving RIP advertisements. Once the unit is in Routing mode, it receives RIP
updates when there is another RIP-enabled device advertising on your network. Although it receives and
processes these updates, it does not further propagate these updates unless configured to advertise RIP.
• The ability to enable or disable default route propagation is not user configurable. Once initialized, the 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 unit. The 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.
