Stub (Ospf Area View) - H3C S5820X Series Command Reference Manual

View
OSPF view
Default Level
2: System level
Parameters
maximum-interval: Maximum OSPF route calculation interval in seconds, in the range 1 to 60.
minimum-interval: Minimum OSPF route calculation interval in milliseconds, in the range 10 to 60000,
which defaults to 0.
incremental-interval: Incremental value in milliseconds, in the range 10 to 60000, which defaults to
5000.
Description
Use the spf-schedule-interval command to set the OSPF SPF calculation interval.
Use the undo spf-schedule-interval command to restore the default.
The interval defaults to 5 seconds.
Based on its LSDB, an OSPF router calculates the shortest path tree with itself being the root, and
uses it to determine the next hop to a destination. Through adjusting the SPF calculation interval, you
can protect bandwidth and router resources from being over-consumed due to frequent network
changes.
With this command configured, when network changes are not frequent, SPF calculation applies at
the minimum-interval. If network changes become frequent, the SPF calculation interval is
incremented by the incremental-interval each time a calculation happens, up to the maximum-interval.
Examples
# Configure the SPF calculation maximum interval as 10 seconds, minimum interval as 500
milliseconds and incremental interval as 200 milliseconds.
