LSA delay time
Each LSA has an age in the local LSDB (incremented by one per second), but an LSA does not age on
transmission. You must add an LSA delay time into the age time before transmission, which is important
for low-speed networks.
SPF timer
Whenever the LSDB changes, an SPF calculation occurs. If recalculations become frequent, a large
amount of resources will be occupied. You can adjust the SPF calculation interval and delay time to
protect networks from being overloaded by frequent changes.
GR timer
If a failure to establish adjacencies occurs during a GR, the device will be in the GR process for a long
time. To avoid this, configure the GR timer for the device to exit the GR process when the timer expires.
