spf-interval-exp
Use this command to set the minimum and maximum hold intervals between Shortest Path First (SPF) calculations.
The spf-interval-exp command configures the minimum and maximum interval time between the receipt of a topology change and the calculation of the SPF.
Use the no parameter with this command to set the minimum and maximum hold intervals to the default.
Command Syntax
spf-interval-exp <0-2147483647> <0-2147483647>
spf-interval-exp (level-1|level-2) <0-2147483647> <0-2147483647>
no spf-interval-exp ((level-1|level-2)|)
Parameters
<0-2147483647>
Specify the minimum delay between receiving a change to the SPF calculation in milliseconds. The default SPF minimum hold-time interval value is 500 milliseconds.
<0-2147483647>
Specify the maximum delay between receiving a change to the SPF calculation in milliseconds. The default SPF maximum hold-time interval value is 50 seconds.
level-1
Specify an interval for Level-1 IS.
level-2
Specify an interval for Level-2 IS.
Default
By default, ISIS uses 500 milliseconds and 50,000 milliseconds for the minimum and maximum hold intervals, respectively. The values are applied to both level-1 and level-2 if the level parameter is omitted.
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 1.3.

#configure terminal
(config)#router isis bb
(config-router)#spf-interval-exp level-1 600 60000
