OSPF Redistribution Rules

Route redistribution is the process of importing a route into the current routing domain from another part of the network that uses another routing protocol. When this occurs, the current domain has to translate all the routing information, particularly known routes, from the other protocol. Note that you must configure at least one route map before you can configure a redistribution rule. For more information, see Route Map Configuration.

To Redistribute Routes into OSPF

Enter the necessary information:

Route Map: The drop-down list displays the previously configured route maps. Select the route map that defines the routes to be redistributed.

Protocol: Specifies the protocol by which the route map determines whether to forward or deny an incoming packet. Select one of the following:

BGP: Specifies that the route map performs an action only on BGP routes in the network.

RIP: Specifies that the route map performs an action only on RIP routes in the network.

Connected: Specifies that the route map performs an action only on directly connected routes.

Imported: Specifies that the route map performs an action only on redistributed routes in the network.

Static: Specifies that the route map performs an action only on static routes in the network.

Click Add to create the redistribution rule.

The new redistribution rule is added to the table.

To Remove a Route Redistribution Rule
