The following task changes the partial shortest path first (PSPF) interval, changing the maximum interval between SPF recalculations, the initial SPF calculation delay, and the hold time between the first and second SPF calculation.
Procedure
-
Enter the
configure terminal command to access global configuration mode.
device# configure terminal
-
Enter the
router isis command to enter IS-IS router configuration mode and enable IS-IS on the device.
device(config)# router isis
-
Enter the
partial-spf-interval command with the
level-1 parameter, specifying values for the
max-wait
,
initial-wait
, and
second-wait
parameters, to set the maximum interval between SPF recalculationss, the initial SPF calculation delay, and the hold time between the first and second SPF calculation.
device(config-isis-router)# partial-spf-interval 15 10000 15000
Example
The following example specifies that the maximum interval in seconds between SPF recalculations is 15 seconds. The initial SPF calculation delay is 10000 milliseconds and the hold time between the first and second SPF calculation is 15000 milliseconds.
device# configure terminal
device(config)# router isis
device(config-isis-router)# partial-spf-interval 15 10000 15000
