Switch 7700 Configuration Guide

OSPF 91
Perform the following configuration in OSPF view.
By default, OSPF does not import the routing information of other protocols.
The protocol variable specifies a source routing protocol that can be imported,
such as direct, static, RIP, or BGP.
Configure Parameters for OSPF to Import External Routes
When OSPF imports the routing information discovered by other routing protocols
in the autonomous system, some additional parameters need configuring, such as
the default route cost and the default tag of route distribution, as described in
Table 42. 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.
By default, no default cost and tag are available when importing external routes,
and the type of the imported route is type-2. The interval of importing the external
route is 1 second. The upper limit to the external routes imported is 1000 per
second.
