information of other protocols
By default, OSPF will not import the routing information of other protocols. The default
type of the imported route is 2, cost is 1, and tag is 1.
protocol specifies a source routing protocol that can be imported. By far, it can be Direct,
Static, RIP or BGP.
Note:
You are recommended to configure both the route type, cost and tag together in one
command; otherwise, the new configuration overwrites the old one.

4.2.22 Configuring Parameters for OSPF to Import External Routes

When the OSPF imports the routing information discovered by other routing protocols
in the autonomous system, some additional parameters need configuring, such as
default route cost and default tag of route distribution, etc. Route ID can be used to
identify the protocol-related information. For example, OSPF can use it to identify the
AS number when receiving BGP.
Perform the following configuration in OSPF view.
