Enter the
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 in seconds between SPF recalculations, the initial SPF calculation delay, and the hold time between the first and second SPF calculation.
device(config-isis-router)# spf-interval level-1 15 10000 15000
The following example specifies that the maximum interval in seconds between SPF recalculations is 15 seconds for Level 1 packets. The initial SPF calculation delay is 10000 milliseconds and the hold time between the first and second SPF calculation is 15000 millseconds.
device# configure terminal
device(config)# router isis
device(config-isis-router)# spf-interval level-1 15 10000 15000
