LSA delay timer
Each LSA has an age in the local link state database (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 happens. If recalculations become frequent, a large
amount of resources are occupied. You can adjust the SPF calculation interval and delay time to protect
networks from being overloaded due to frequent changes.
GR timer
If a failure to establish adjacencies occurs during a GR, the device is 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.
