Configuration | System | IP Routing | OSPF Areas
This section of the Manager lets you configure OSPF areas, which are the subnets within an OSPF
Autonomous System or domain. You should configure entries for all areas connected to this VPN
Concentrator OSPF router.
You can also identify an OSPF area on a VPN Concentrator network interface (see Configuration |
Interfaces). Those area identifiers appear in the OSPF Area list on this screen.
Figure 8-6: Configuration | System | IP Routing | OSPF Areas screen

OSPF Area

The OSPF Area list shows identifiers for all areas that are connected to this VPN Concentrator OSPF
router. The format is the same as a dotted decimal IP address; e.g., 10.10.0.0. The default entry is
0.0.0.0, which identifies a special area—the backbone—that contains all area border routers, which
are the routers connected to multiple areas.
