Usage Guide
Each LSA has its own lifetime, that is, LSA aging time. An LSA existing for 1800s will be refreshed so
that the living time of the LSA will not exceed its aging time. This ensures that normal LSAs are not
cleared due to timeout of aging time
.
If update and aging operations of each LSA are separately
computed, a large number of CPU resources will be consumed.
To effectively utilize CPU resources, configure the device to group LSAs for uniform refreshment. The
time for refreshing a group of LSAs is called an LSA group pace interval. Grouping refreshment is to
put the LSAs to be refreshed within an LSA group pace interval into a group and refresh them
uniformly.
When the number of LSAs is fixed, a longer LSA group pace interval will allow the CPU to process
more LSAs when the timer expires for one time. To keep the stability of the CPU, you are
recommended not to set an over long LSA group pace interval. This prevents the CPU from
processing excessive LSAs when the timer expires each time. If the CPU processes a large number
of LSAs each time, it is recommended to shorten the LSA group pace interval. For example, if the
database has 10000 LSAs, you need to reduce the LSA group pace interval. If it has only 40 to 100
LSAs, you can adjust the group pace interval to 10 through 20 minutes.
Configuration
The following example sets the LSA group pace interval to 120 seconds.
