Command
History
Usage
Information
This command
spf-interval
in CONFIG-ROUTER-ISIS-AF-IPV6 mode is used for IPv6
Multi-Topology route computation only. If using single topology mode, use the
spf-interval
command in CONFIG-ROUTER-ISIS mode for both IPv4 and IPv6 route computations.
SPF throttling slows down the frequency at which route calculation are performed during network
instability. Even though throttling route calculations slows down network convergence, not throttling
can result in a network not functioning as expected. If network topology is unstable, throttling slows
down the scheduling of route calculations until the topology regains its stability.
The first route calculation is controlled by the initial wait interval and the second calculation is
controlled by the second wait interval. Each subsequent wait interval is twice as long as the previous
one until the wait interval reaches the maximum wait time specified (
interval seconds
). Once the
network calms down and there are no triggers for two times the maximum interval, fast behavior is
restored (the initial wait time).
level-l
(OPTIONAL) Enter the keyword
level-1
to apply the configuration to
Level-1 SPF calculations.
level-2
(OPTIONAL) Enter the keyword
level-2
to apply the configuration to
Level-2 SPF calculations.
interval seconds
Enter the maximum number of seconds between SPF calculations.
Range: 0 to 120 seconds
Default: 10 seconds
initial_wait_interval
seconds
(OPTIONAL) Enter the initial wait time, in seconds, before running the first
SPF calculations.
Range: 0 to 120 seconds
Default: 5 second
second_wait_interval
seconds
(OPTIONAL) Enter the wait interval, in seconds, between the first and
second SPF calculations.
Range: 0 to 120 seconds
Default: 5 seconds
Version 7.8.1.0
Introduced to support MT ISIS
Version 7.5.1.0
