lsp-gen-interval

Set the minimum interval between successive generations of link-state packets (LSPs).

Syntax

lsp-gen-interval [level-l | level-2] interval seconds [ initial_wait_interval seconds [ second_wait_interval seconds ]]

To restore default values, use the no lsp-gen-interval [level-l | level-2] interval seconds [ initial_wait_interval seconds [ second_wait_interval seconds]] command.

Parameters

level-l	(OPTIONAL) Enter the keywords `level-1` to apply the configuration to generation of Level-1 LSPs.
level-2	(OPTIONAL) Enter the keywords `level-2` to apply the configuration to generation of Level-2 LSPs.
interval seconds	Enter the maximum number of seconds between LSP generations. The range is from 0 to 120 seconds. The default is 5 seconds.
initial_wait_interval seconds	(OPTIONAL) Enter the initial wait time, in seconds, before running the first LSP generation. The range is from 0 to 120 seconds. The default is 1 second.
second_wait_interval seconds	(OPTIONAL) Enter the wait interval, in seconds, between the first and second LSP generation. The range is from 0 to 120 seconds. The default is 5 seconds.

Usage Information

LSP throttling slows down the frequency at which LSPs are generated during network instability. Even though throttling LSP generations slows down network convergence, no throttling can result in a network not functioning as expected. If network topology is unstable, throttling slows down the scheduling of LSP generations until the topology regains its stability.

The first generation is controlled by the initial wait interval and the second generation 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). After the network calms down and there are no triggers for two times the maximum interval, fast behavior is restored (the initial wait time).
