By default, OSPF does not import routes from other domains into the routing table.

The protocol attribute specifies the source routing domain that can be imported.

At present, OSPF can import routes domain such as connected, static, RIP, and

BGP.

See“Configuring Route Import for OSPF” for the details of routing import.

Configuring Parameters When the routes found by other routing protocols on the router are received by when Importing OSPF as the external routing information of its own AS, some other parameters External Routes are needed, including the default cost and default tag of the route. Router tag can

be used to identify the information related to the protocol, such as the number OSPF uses as the AS number when receiving BGP protocol.

OSPF specifies two types of cost selection modes of external routing information in the protocol. You can configure receiving the default cost type of the route.

Perform the following configurations in OSPF view.
