	[ level-1 level-2 ]

View	IS-IS view
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-generationcommand to specify intervals for ISIS LSP
	generation.
	Use the undo timer isp-generationcommand to restore the default.
	By default, the LSP generation interval is 2 seconds.
n	■ 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.
