timer lsp-generation

Use timer lsp-generation to set the LSP generation interval.

Use undo timer lsp-generation to remove the configuration.

Syntax

timer lsp-generation maximum-interval [ minimum-interval [ incremental-interval ] ] [ level-1 | level-2 ]

undo timer lsp-generation [ level-1 | level-2 ]

Default

The maximum interval is 5 seconds, the minimum interval is 50 milliseconds, and the incremental interval is 200 milliseconds.

Parameters

maximum-interval: Specifies the maximum interval in the range of 1 to 120 seconds.

minimum-interval: Specifies the minimum interval in the range of 10 to 60000 milliseconds.

incremental-interval: Specifies the incremental interval in the range of 10 to 60000 milliseconds.

level-1: Applies the intervals to Level-1.

level-2: Applies the intervals to Level-2. If no level is specified, the specified intervals apply to both Level-1 and Level-2.

Usage guidelines

By adjusting the LSP generation interval, you can prevent bandwidth and router resources from being over consumed due to frequent topology changes.

If you specify only the maximum-interval argument, the LSP generation interval is maximum-interval.

If you do not specify the incremental-interval argument, the LSP generation interval is in the range of minimum-interval to maximum-interval.

If you specify the incremental-interval argument, the LSP generation interval is as follows:

• When network changes are not frequent, the minimum-interval is adopted.

• When network changes are frequent, the LSP generation interval increases by incremental-interval × 2^n-2 (n is the number of calculation times) each time a generation occurs until the maximum-interval is reached.

The minimum interval and the incremental interval cannot be greater than the maximum interval.

Examples

# Set the maximum interval, minimum interval, and incremental interval to 10 seconds, 100 milliseconds, and 200 milliseconds, respectively.
