DMS-3130 Series Multi-Gigabit L3 Stackable Managed Switch Web UI Reference Guide Parameter Descriptionx neighbor router, as the user configures a new key, the router will start the roll over process by sending duplicated packets for both of the old and the new key. The router will stop sending duplicated packets until it finds that all routers on the network have learned the new key. After the rollover process completed, the user should delete the old key to prevent the router from communicating with the router using the old key. Click the Apply button to accept the changes made. OSPFv2 Redistribute Settings This window is used to display and configure the OSPFv2 redistribution settings. External routes can be redistributed to normal areas as Type-5 external routes and redistributed to NSSA stub areas as Type-7 external routes by the ASBR. If the redistributed external route is of Type-1, the metric represents the internal metric. If the redistributed external route is of Type-2, the metric represents the external metric. An internal metric will consider the cost of the route from itself to the redistributing router plus the advertised cost to reach the destination. An external metric only considers the advertised metric to reach the destination. If no metric value is specified by the default metric, routes redistributed from other protocols will get a metric value of 20. To view the following window, click L3 Features > OSPF > OSPFv2 > OSPFv2 Redistribute Settings, as shown below: Figure 6-45 OSPFv2 Redistribute Settings Window The fields that can be configured are described below: Parameter Protocol Metric Type Metric Router Map Name Description Select the source protocol that will be redistributed here. Options to choose from are Connected, Static and RIP. For routing protocols like Open Shortest Path First (OSPF), these routes will be redistributed as external to the autonomous system. Select the metric type here. Options to choose from are External Type-1 and External Type-2. This specifies the external link type of the route being redistributed into the OSPF routing domain. By default, the Switch will adopt a Type-2 external route. Enter the metric value for the redistributed routes here. The range is from 1 to 16777214. Enter the route map name here that filters the imported routes from this source routing protocol. If not specified, all routes are redistributed. 235
