Usage
This command configures the minimum and maximum delay time between the
receipt of a topology change and the calculation of the Shortest Path First (SPF).
The time between SPF runs increases if a topology change occurs (and triggers a
new SPF run) before the last SPF holdtimer has finished. The time between runs
may increase up to the max-holdtime value.This increase in holdtime prevents too
many SPF runs from occurring if multiple OSPF topology change events occur.
Examples
To set the minimum delay time to 5 milliseconds and maximum delay time to 2
seconds, use the commands:
awplus#
configure terminal
awplus(config)#
router ipv6 ospf 100
awplus(config-router)#
timers spf exp 5 2000

Parameter
Description
<
min-holdtime
>
Specifies the minimum delay between receiving a change to the
SPF calculation in milliseconds. The range is 0-2147483647. The
default SPF min-holdtime value is 50 milliseconds.
<
max-holdtime
>
Specifies the maximum delay between receiving a change to the
SPF calculation in milliseconds. The range is 0-2147483647. The
default SPF max-holdtime value is 50 seconds.
