Parameter | Description |
OSPF Protocol | Enables OSPF on all interfaces. |
Router ID | Assigns a unique ID to the router for use by the OSPF protocol. It must be one of the |
| router's IP addresses. |
AS Boundary Router | An Autonomous System Boundary Router (ASBR) can convert external routes into |
| OSPF routes. Which external routes is determined through the following parameters. |
| In the figure, only Router 5 is an ASBR. |
The following parameters | apply only to Autonomous System Boundary Routers. |
Originate Default | Router will advertise itself as the Default Gateway (DG). |

Default Gateway | Applies when Originate Default Gateway Advertisement is set to Yes. Defines the |
External Metric | metric that will be advertised by OSPF. |
Default Gateway | Applies when Originate Default Gateway Advertisement is set to Yes. For Type 1, the |
External | total metric of this route is composed of the internal metric (inside the autonomous |
| system) and the external metric (provided in the previous parameter). For Type 2, the |
| total metric of this route is the value provided in the previous parameter. |
