Function

The spf timers command sets the interval for calculating OSPFv3 routes by a common SPF timer.

Format

spf timers delay-interval hold-interval

undo spf timers

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 hold interval between two consecutive SPF calculations. The value is an integer ranging from 0 to 65535 seconds. By default, it is 10 seconds.

Default Level

2: Configuration level

Usage Guidelines

According to the local LSDB, the switch that runs OSPFv3 can calculate a 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 switch sources caused by frequent change of the network.

NOTE:
A common SPF timer and an intelligent SPF timer are mutually exclusive.

Example

# Set both the OSPFv3 route calculation interval and the hold interval to 6 seconds.
