Timer Spf - HP FlexFabric 5930 Series Command Reference Manual

Parameters
seconds: Specifies the LSP refresh interval in the range of 1 to 65534 seconds.
Usage guidelines
To prevent LSPs from age-out and synchronize LSDBs, ISIS-SPB performs periodic LSP update. The LSP
refresh interval sets the interval at which ISIS-SPB regularly regenerates an LSP, regardless of whether
any change has occurred to the LSP.
A short refresh interval improves network convergence time, but it also uses more bandwidth resources
and system resources.
To avoid unnecessary LSP age-outs, make sure the LSP refresh interval is shorter than the LSP lifetime.
Examples
# Set the LSP refresh interval to 1200 seconds.
