Redistributing Routes Into OSPF
The adaptive security appliance can control the redistribution of routes between OSPF routing processes.
Note If you want to redistribute a route by defining which of the routes from the specified routing protocol are
allowed to be redistributed into the target routing process, you must first generate a default route. See
the “Configuring Static and Default Routes” section on page 19-2 and then define a route map according
to the “Defining a Route Map” section on page 20-4.
To redistribute static, connected, RIP, or OSPF routes into an OSPF process, perform the following steps:
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > OSPF >
Redistribution.
The Redistribution pane displays the rules for redistributing routes from one routing process into an
OSPF routing process. You can redistribute routes discovered by RIP and OSPF into the EIGRP routing
process. You can also redistribute static and connected routes into the EIGRP routing process. You do
not need to redistribute static or connected routes if they fall within the range of a network that has been
configured through the Setup > Networks tab.
Step 2 Choose Add or Edit.
Alternatively, double-clicking a table entry in the Redistribution pane (if any) opens the Add/Edit OSPF
Redistribution Entry dialog box for the selected entry.
Note All steps that follow are optional.
The Add/Edit OSPF Redistribution Entry dialog box lets you add a new redistribution rule to or edit an
existing redistribution rule in the Redistribution table. Some of the redistribution rule information cannot
be changed when you are editing an existing redistribution rule.
Step 3 Choose the OSPF process associated with the route redistribution entry. If you are editing an existing
redistribution rule, you cannot change this setting.
Step 4 Choose the source protocol from which the routes are being redistributed. You can choose one of the
following options:
