H3C S7500 Series Ethernet Switches Chapter 3 OSPF Configuration Commands
3-6
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 interval.
OSPF can import external routing information and propagate it to the entire
autonomous system. However, importing routes too often greatly affects the
performance of the device. Therefore, it is necessary to specify the default interval for
the protocol to import external routes.
Examples
# Specify the default interval for OSPF to import external routes as 10 seconds.
<H3C> system-view
System View: return to User View with Ctrl+Z.
[H3C] ospf 1
[H3C-ospf-1] default interval 10
3.1.7 default limit
Syntax
default limit routes
undo default limit
View
OSPF view
Parameters
routes: Number of external routes that can be imported in a unit time. The value ranges
from 200 to 2,147,483,647 and defaults to 1,000.
Description
Use the default limit command to configure the number of routes that can be imported
by OSPF in a unit time.
Use the undo default limit command to restore the default value.
OSPF can import external routing information and advertise them to the whole AS.
However, importing too many external routes at a time greatly affects the performance
of the device. Therefore, it is necessary to set number of external routes that can be
imported during each import interval.
