config router ospf
Use this command to configure OSPF. FortiADC supports OSPF version 2.
OSPF (Open Shortest Path First) is described in RFC2328, OSPF Version 2. It is a link-state interior routing protocol. Compared with RIP, OSPF can provide scalable network support and faster convergence times. OSPF is widely used in large networks such as ISP backbone and enterprise networks.
Before you begin:
• You must have read-write permission for system settings.

router-id | 32-bit number that identifies the router. The router ID uses dotted decimal notation. sets the router-ID of the OSPF process. The router-ID must be an IP address of the router, and it must be unique within the entire OSPF domain to the OSPF speaker. |
default-metric | The default is 10. |
distance | The default is 110. |
default-information-originate | • enable—Originate an AS-External (type-5) LSA describing a default route into all external routing capable areas of the specified metric and metric type. • always—The default is always advertised, even when there is no default present in the routing table. • disable |
default-information-metric-type | • 1 • 2 |
default-information-metric | The default is -1. |
redistribute-connected | Enable/disable to redistribute connected routes into OSPF, with the metric type and metric set if specified. Redistributed routes are distributed into OSPF as Type-5 External LSAs into links to areas. |
redistribute-connected-metric-type | • 1 • 2 |
redistribute-connected-metric | Specify a metric. |
redistribute-static | Enable/disable to redistribute static routes into OSPF, with the metric type and metric set if specified. Redistributed routes are distributed into OSPF as Type-5 External LSAs into links to areas. |
redistribute-static-metric-type | • 1 • 2 |
redistribute-static-metric | Specify a metric. |
config network |
area | 32-bit number that identifies the OSPF area. An OSPF area is a smaller part of the larger OSPF AS. Areas are used to limit the link-state updates that are sent out. The flooding used for these updates would overwhelm a large network, so it is divided into these smaller areas for manageability. |
prefix | Address/mask notation to specify the subnet. |
config ospf-interface |
cost | Set link cost for the specified interface. The cost value is set to router-LSA's metric field and used for SPF calculation. The default is 0. |
dead-interval | Number of seconds for RouterDeadInterval timer value used for Wait Timer and Inactivity Timer. This value must be the same for all routers attached to a common network. The default is 40 seconds. |
hello-interval | Number of seconds between hello packets sent on the configured interface. This value must be the same for all routers attached to a common network. The default is 10 seconds. |
interface | Specify the interface to enable OSPF for it. |
mtu-ignore | Enable/disable to ignore the interface MTU. Disabled by default. |
network-type | • broadcast • point-to-point • point-to-multipoint |
priority | The router with the highest priority will be more eligible to become Designated Router. Setting the value to 0 makes the router ineligible to become Designated Router. The default is 1. |
retransmit-interval | Interval for retransmitting Database Description and Link State Request packets. The default is 5 seconds. |
transmit-delay | Increment LSA age by this value when transmitting. The default is 1 second. |
