virnbrstatechange: Virtual interface neighbor state change information.
Description
Use the snmp-agent trap enable ospf command to enable the sending of SNMP traps for a specified
OSPF process. If no process is specified, the feature is enabled for all processes.
Use the undo snmp-agent trap enable ospf command to disable the feature.
By default, this feature is enabled.
For related configurations, see SNMP Commands in System Management and Maintenance Command

spf-schedule-interval
Syntax
spf-schedule-interval maximum-interval [ minimum-interval [ incremental-interval ] ]
undo spf-schedule-interval
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.
