HP MSR2000/3000/4000 Router Series Layer 3 - IP Routing Command Reference

259
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.
When network changes are not frequent, the minimum-interval is adopted. If network changes become
frequent, the LSP generation interval is incremented by the incremental-interval 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.

timer lsp-max-age
Use timer lsp-max-age to set the LSP maximum age in the LSDB.
Use undo timer lsp-max-age to restore the default.
Syntax
timer lsp-max-age seconds
undo timer lsp-max-age
Default
The LSP maximum age is 1200 seconds.

Parameters
seconds: Specifies the LSP maximum aging time in the range of 1 to 65535 seconds.
Usage guidelines
Each LSP has an age that decreases in the LSDB. Any LSP with an age of 0 is deleted from the LSDB. You
can adjust the age value based on the scale of a network.
Examples
# Set the maximum LSP age to 1500 seconds.
