configure router isis spf-interval
Configures the IS-IS throttling of shortest path first (SPF) calculations.
configure router isis spf-interval <time> [start-spf-calc <0-1000 | none | infinite>] [calc-pause-freq
<0-4294967294 | none | infinite>]
configure router isis spf-interval no
To restore the default value, use the no option.
Parameters
The maximum delay before the Routing Table is recalculated following a change to the Link State Database. (Recalculation is delayed
to reduce the frequency of recalculations of the Routing Table). This parameter has units of milliseconds.
A value of 0 indicates that a routing calculation will immediately follow an update to the database. The default is 5000 milliseconds.
[start-spf-calc <0-
1000 | none |
infinite>]
This parameter can be used to override the routing calculation delay when the number of updates to the Link State Database
reaches a threshold value.
0-1000 - specifies the threshold number of updates that can be made to the Link State Database such that any subsequent update to
the database causes a full routing calculation to start immediately.
None - indicates that an update to the Link State Database will cause any current routing calculation to be interrupted and a new
one to start.
Infinite - indicates that this threshold is infinite and hence no number of pending updates to the database will cause a routing
calculation to be interrupted.
