Parameters
maximum-interval: Specifies the maximum LSP generation interval in the range of 1 to 120 seconds.
minimum-interval: Specifies the minimum LSP generation interval in the range of 10 to 60000
milliseconds. This setting must be smaller than the maximum interval.
incremental-interval: Specifies the base number for the incremental interval. The value range is 10 to
60000 milliseconds. This setting must be smaller than the maximum interval.
Usage guidelines
The LSP generation timer sets the delay for ISIS-SPB to generate a new version of an LSP in response to
an LSP change. For example, an update occurs because of a change in adjacency, interface metric
value, system ID, or area address.
The LSP generation timer is an exponential generation timer. With this timer, ISIS-SPB quickly responds
to the first events for an LSP and then slows down to protect the CPU from frequent LSP generation.
When the network is stable, the LSP generation timer is set to the minimum interval for each LSP
generation.

maximum interval is reached. If an event triggers LSP generation after the maximum interval is reached,
the LSP generation timer re-initiates with the minimum interval.
NOTE:
The network is considered unstable if the interval between consecutive LSP generation events is smaller
than two times the maximum interval.
Examples
# Set the maximum LSP generation interval, the minimum LSP generation interval, and the base number
for the incremental interval to 10 seconds, 100 milliseconds, 200 milliseconds, respectively.

timer lsp-max-age

Use timer lsp-max-age to specify the maximum lifetime of LSPs.
Use undo timer lsp-max-age to restore the default.
