82 Chapter 10. Routing • Exporting routes from the routing table to OSPF process. • Exporting routes from one OSPF process to another OSPF process. 10.5.3 Scenarios: Dynamic Routing Configuration In this section, basic scenarios for using OSPF Process and Dynamic Routing Policy are illustrated. Example: Setting up OSPF process Figure 10.2: OSPF Process Scenario As shown in Figure 10.2 , the firewall is assumed to have an interface "lan3" connected to a couple of local networks, which the firewall will control the only path into; and 2 interfaces, "lan1" and "lan2" attached to a larger local network. Some of the networks will be accessible through both interfaces, so that some redundancy might be achieved if one path becomes unreachable. This is done by placing the two interfaces "lan1" and "lan2" into a security equivalent interface group. An OSPF process named as "ospf-proc1" is created, and only one OSPF area, the backbone "area0" (0.0.0.0), is used in this example. The 3 involved interfaces are added into the area to make the firewall participate in the OSPF process. However, this will not add any learned routes into any routing table, nor will it inform its neighbor about any static routes in its routing table(s)(except the routes for the 3 interfaces participating in this OSPF process). To control this information exchange, dynamic routing D-Link Firewalls User's Guide
