Description
Using spf-schedule-interval command, you can configure the route calculation
interval of OSPF. Using 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.
