Command Manual – IPv4 Routing
H3C S7500E Series Ethernet Switches
If an LSA that has the same LSA type, LS ID, originating router ID with the previous LSA
is received within the interval, the LSA will be discarded. This feature helps protect
routers and bandwidth from being over-consumed due to frequent network changes.
It is recommended the interval set with the lsa-arrival-interval command is smaller or
equal to the initial interval set with the lsa-generation-interval command.
Related commands: lsa-generation-interval.
Examples
# Set the LSA minimum repeat arrival interval to 200 milliseconds.

3.1.32 lsa-generation-interval
Syntax
lsa-generation-interval maximum-interval [ initial-interval [ incremental-interval ] ]
undo lsa-generation-interval
View
OSPF view
Parameters
maximum-interval: Maximum LSA generation interval in seconds, in the range 1 to 60.
initial-interval: Minimum LSA generation interval in milliseconds, in the range 10 to
60000. The default is 0.
incremental-interval: LSA generation incremental interval in milliseconds, in the range
10 to 60000. The default is 5000 milliseconds.
Description
Use the lsa-generation-interval command to configure the OSPF LSA generation
interval.
Use the undo lsa-generation-interval command to restore the default.
The LSA generation interval defaults to 5 seconds.
With this command configured, when network changes are not frequent, LSAs are
generated at the initial-interval. If network changes become frequent, LSA generation
interval is incremented by a specified value each time a generation happens, up to the
maximum-interval.
Related commands: lsa-arrival-interval.
