In order to configure OSPF with LANconfig, navigate to the menu.
- Open Shortest Path First (OSPF) enabled
- To activate the OSPF function, set a check mark for Open Shortest Path First (OSPF) enabled.
- OSPF instance
- The table OSPF instance defines the OSPF instances on this device. It is possible for a device to operate multiple OSPF instances in parallel. Each instance corresponds to an autonomous system or an OSPF domain.
- OSPF areas
- The table OSPF areas is used to define the parameters of the OSPF areas.
- OSPF interfaces
- This table specifies the interfaces on which OSPF is to operate.
- NBMA neighbors
- Non-broadcast multi-access networks are networks containing multiple routers, but where broadcast is not supported. In this type of network, OSPF emulates operations in a broadcast network. A default router is selected for this network type.Note: The communication takes place not by multicast, but by unicast. Neighborhood connections must be configured manually, as the routers are unable to discover one another automatically by multicast.
- Point-to-multipoint neighbors
- In a point-to-multipoint network, all neighbors are treated as if point-to-point neighbors were directly connected via a non-broadcast network. If no default router is selected, multicast is used for communications instead.
- Virtual links
- This table is used to define virtual links (also referred to as transit area). In principle, OSPF requires all areas to be directly connected to the backbone area. Virtual links can be used in cases where this is not possible. A virtual link uses a non-backbone area to connect a router to the backbone area.
- Area address aggregation
- In order to reduce the number of entries in the routing tables, IP addresses can be grouped by address aggregation at the borders transitioning from the backbone area to non-backbone areas. The corresponding subnet is advertised as a summary LSA.
- BGP
- Routes learned dynamically from BGP sources or protocols can be distributed by OSPF.
- Connected
- Connected routes, i.e. routes that the operating system automatically enters into the routing table, can be redistributed by OSPF.
- Static
- Static routes, i.e. routes that the user manually enters into the routing table, can be redistributed by OSPF.
