Static Reject Routes A static reject route is a static route to discard the packets to a particular destination, thereby forcing a black-hole routing behavior for a particular set of IP prefixes. Static reject routes can help prevent a routing loop in the network if a default route is configured on a router. Static reject routes also help protect against a DOS attack on a router with unwanted destination addresses. NOTE: Static reject routes are not redistributed by OSPF or RIP. Starting with software release 3.0, you can select Static Reject as a route type from the Route Type field on the following pages under the Routing > Router menu: • Route Entry Configuration • Configured Routes NOTE: For a static reject route, the next hop interface value is Null0. Packets to the network address specified in static reject routes are intentionally dropped. To display the page, click Routing > RIP > Route Redistribution Configuration in the tree view. Figure 9-31. RIP Route Redistribution Configuration The RIP Route Redistribution Configuration page contains the following fields: • Source - Select the type of source route to configure for redistribution by RIP. Possible values are: - Static - Connected - OSPF • Metric - Sets the metric value to be used as the metric of redistributed routes. This field displays the metric if the source was pre-configured and can be modified. The valid values are 1 to 15. • Distribute List - Select the Access List that filters the routes to be redistributed by the destination protocol. Only permitted routes are redistributed.
