Dynamic Routing Rule Objects - D-Link DFL-1660 User Manual

4.5.4. Dynamic Routing Rules
OSPF Requires at Least an Import Rule
By default, NetDefendOS will not import or export any routes. For OSPF to function, it is therefore
mandatory to define at least one dynamic routing rule which will be an Import rule.
This Import rule specifies the local OSPF Router Process object. This enables the external routes
made available in the OSPF AS to be imported into the local routing tables.
Specifying a Filter
Dynamic routing rules allow a filter to be specified which narrows the routes that are imported
based on the network reached. In most cases, the Or is within option should be specified as all-nets
so that no filter is applied.
When to Use Export Rules
Although an Import rule is needed to import routes from the OSPF AS, the opposite is not true. The
export of routes to networks that are part of OSPF Interface objects are automatic.
A dynamic routing export rule must be created to explicitly export the route to the OSPF AS.
