Parameters
interval: SPF calculation interval of OSPF, in seconds. It ranges from 1 to 10.
Description
Use the spf-schedule-interval command to configure the SPF calculation interval of OSPF.
Use the undo spf-schedule-interval command to restore the default.
By default, the SPF calculation interval of OSPF is 5 seconds.
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. Adjusting SPF calculation interval restrains frequent network changes, which may
occupy too many bandwidth resources and router resources.
Examples
# Set the OSPF route calculation interval of H3C to 6 seconds.
