Global OSPFv2 Configuration

•
OSPF Router ID—The Router ID can be any value, represented in IP address notation. It is unrelated to the any of the IP addresses on the SonicWall, and can be set to any unique value within your OSPF network.
•
ABR Type—Allows for the specification of the topology with which this OSPF router will be participating, for the sake of compatibility. The options are:
•
Standard—Full RFC2328 compliant ABR OSPF operation.
•
Cisco—For interoperating with Cisco’s ABR behavior, which expects the backbone to be configured and active before setting the ABR flag. This is the default.
•
IBM—For interoperating with IBM’s ABR behavior, which expects the backbone to be configured before settings the ABR flag.
•
Shortcut—A ‘shortcut area’ enables traffic to go through the non-backbone area with a lower metric whether or not the ABR router is attached to area 0.
•
Default Metric—Used to specify the metric that will be used when redistributing routes from other (Default, Static, Connected, RIP, or VPN) routing information sources. The default value is Undefined, the minimum value is 1, and the maximum is 16777214.
•
Auto-Cost Reference BW (Mb/s)—Used to change the auto-cost reference bandwidth formula to account for different platform bandwidths. The default value is 100.
•
Originate Default Route—Controls the advertising of the SonicWall security appliance’s default route into the OSPF system on this interface. The options are:
•
Never—Disables advertisement of the default route into the OSPF system. This is the default.
•
When WAN is up—Advertises the default route into the OSPF system when the WAN is online. The default route is always advertised as an External Type 2 using LSA Type 5.
•
Always—Enables advertisement of the default route into the OSPF system. The default route is always advertised as an External Type 2 using LSA Type 5.
* 
NOTE: These options applies to all the following Redistributed routes:

The metric can be explicitly set for the redistribution, or it can use the value specified in the Default Metric setting. The minimum is 1, the maximum is 16777214, and the default is Default (the value in the Default Metric setting.

In the Tag field, an optional route tag value can be added to help other routers identify this redistributed route. The default tag value is Undefined, the minimum is 0, and the maximum is 4294967295.

The redistributed route advertisement will be an LSA Type 5, and the type may be selected from the Metric Type drop-down menu as either Type 1 (adds the internal link cost) or Type 2 (only uses the external link cost).

•
Redistribute Static Routes—Enables or disables the advertising of static (Policy Based Routing) routes into the OSPF system.
•
Redistribute Connected Networks—Enables or disables the advertising of locally connected networks into the OSPF system.
•
Redistribute RIP Routes—Enables or disables the advertising of routes learned via RIP into the OSPF system.
•
Redistribute Remote VPN Networks—Enables or disables the advertising of static (Policy Based Routing) routes into the RIP system.
