Parameters
maximum-interval: Maximum interval in seconds for generating ISIS LSPs, in the range
1 to 120.
initial-interval: Initial interval in milliseconds for generating ISIS LSPs, in the range 10 to
60000. The default is 0.
incremental-interval: Incremental interval (in milliseconds), in the range 10 to 60000.
The default is 0.
level-1: Applies the specified intervals to generating level-1 LSPs.
level-2: Applies the specified intervals to generating level-1 LSPs.
Description
Use the timer lsp-generation command to specify intervals for ISIS LSP generation.
Use the undo timer isp-generation command to restore the default.
By default, the LSP generation interval is 2 seconds.
Note:
If only the maximum interval is specified, this maximum interval is the LSP
generation interval.
If both the maximum and initial intervals are specified, the system can adjust the
LSP generation interval upon topology changes. When the topology is stable, the
initial interval applies as the LSP generation interval. When topology changes
become frequent, the LSP generation interval is the maximum or initial interval.
If all the maximum, initial and incremental intervals are specified, the system will
adjust the LSP generation interval upon topology changes in this way: when the
network changes are infrequent, the initial interval applies as the LSP generation
interval. When the network changes become frequent, the generation interval
changes between the initial and maximum intervals based on the specified
incremental interval.
By using this command to adjust the LSP generation interval, you can save the
bandwidth and router resources that may be wasted due to frequent network changes.
