Parameter
seconds: Default interval in seconds for importing external routes. It ranges from 1
to 2,147,483,647 and defaults to 1.
Description
Use the default interval command to configure the default interval for OSPF to
import external routes.
Use the undo default interval command to restore the default value of the
default interval for importing external routes.
Because OSPF can import the external routing information and broadcast it to the
entire autonomous system, and importing routes too often will greatly affect the
performances of the device, it is necessary to specify the default interval for the
protocol to import external routes.
Example
# Specify the default interval for OSPF to import external routes as 10 seconds.
[3Com-ospf-1] default interval 10

OSPF can import external routing information and advertise them to the whole AS.
Importing too much external routes once will greatly affect the performances of
the device.
