Parameter
Interval: SPF calculation interval of OSPF, which is in seconds in the range of 1
to 10. The default value is 5 seconds.
Description
Using the spf-schedule-interval command, you can configure the route calculation
interval of OSPF. Using the undo spf-schedule-interval command, you can restore
the default setting.
According to the Link State Database (LSDB), the router running OSPF can
calculate the shortest path tree taking itself as the root and determine the next
hop to the destination network according to the shortest path tree. By adjusting
SPF calculation interval, network frequently changing can be restrained, which
may lead to that too many bandwidth resources and router resources will be used.
Example
Set the OSPF route calculation interval of 3Com to 6 seconds.
