RIP Parameters (Routing Mode Only)
Routing Internet Protocol (RIP) is a dynamic routing protocol you can use to help automatically propagate routing table
information between routers. The unit can be configured as RIPv1, RIPv2, RIPv1 Compatible, or a combination of the
three versions while operating in Routing mode. In general, the unit’s RIP module is based upon RFC 1389.
NOTE: RIP is configurable only when the unit is in Routing Mode and Network Address Translation (NAT) is disabled.
Note the following:
• 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 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.
