Modifying the Default Timers

OSPFv3 includes a number of timers that control the behavior of protocol messages and shortest path
first (SPF) calculations. OSPFv3 includes the following optional timer parameters:
•
•
•
•
At the interface level, you can also control the following timers:

7-34
LSA arrival time—Sets the minimum interval allowed between LSAs arriving from a neighbor.
LSAs that arrive faster than this time are dropped.
Pacing LSAs—Set the interval at which LSAs are collected into a group and refreshed,
checksummed, or aged. This timer controls how frequently LSA updates occur and optimizes how
many are sent in an LSA update message (see the
page 7-7).
Throttle LSAs—Set rate limits for generating LSAs. This timer controls how frequently an LSA is
generated if no topology change occurs.
Throttle SPF calculation—Controls how frequently the SPF calculation is run.
Retransmit interval—Sets the estimated time between successive LSAs.
Transmit delay—Sets the estimated time to transmit an LSA to a neighbor.
