spf timers
Function
The spf timers command sets the interval for calculating OSPFv3 routes by a common SPF timer.
The undo spf timers command restores the default setting.
Parameters
| Parameter | Description | Value |
|---|---|---|
| delay-interval | Specifies the delay for OSPFv3 from receiving network changes to performing SPF calculation. | The value is an integer ranging from 0 to 65535 seconds. By default, it is 5 seconds. |
| hold-interval | Specifies the holding interval between two consecutive SPF calculations. | The value is an integer ranging from 0 to 65535 seconds. By default, it is 10 seconds. |
Usage Guidelines
By default, the intelligent timer takes effect.
According to the local LSDB, the router that runs OSPFv3 can calculate an SPT with itself as the root and determines the next hop to the destination network according to the SPT. Adjusting SPF calculation interval can avoid the exhaustion of bandwidth and router sources caused by frequent change of the network.
A common SPF timer and an intelligent SPF timer
are mutually exclusive.
