3. Enable FSPF in the VSAN.
fspf enable
By default, FSPF is enabled after a VSAN is
created.
Setting the shortest SPF calculation interval
SPF calculations occur when the LSDB changes. To limit the amount of CPU resources consumed by
frequent SPF calculations, you can change the shortest SPF calculation interval.
The shortest SPF calculation interval defines the minimum interval between two consecutive SPF
calculations. A smaller value means that FSPF responds faster to fabric changes by recalculating routes
in a VSAN, but it requires more CPU resources.
To set the shortest SPF calculation interval:

3. Set the shortest SPF
calculation interval.
fspf spf-hold-time value The default setting is 0 seconds.
Setting the minimum LSR arrival interval
The minimum LSR arrival interval specifies the interval between received LSR updates in a VSAN. Any LSR
updates that arrive before this interval are dropped. This helps avoid frequent SPF calculations caused by
LSDB updating.

3. Set the minimum LSR
arrival interval.
fspf min-ls-arrival value The default setting is 1 second.
Setting the minimum LSR refresh interval
The minimum LSR refresh interval specifies the interval at which LSRs are refreshed. To reduce SPF
calculations and LSR flooding in a fabric caused by frequent LSR refreshing, the switch cannot refresh
local LSRs within this interval.
