Parameter
interval: SPF calculation interval of OSPF, which is in the range of 1 to 10 and is
measured in seconds. The default value is five seconds.
Description
Use the spf-schedule-interval command to configure the route calculation
interval of OSPF.
Use the undo spf-schedule-interval command to 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, frequent network change can be restrained, which may
lead to excessive bandwidth and router resource consumption.
Example
# Set the OSPF route calculation interval of 3Com to six seconds.
[3Com-ospf-1] spf-schedule-interval 6
