Usage Information
Change the maximum LSP lifetime with this command. The maximum LSP lifetime
must always be greater than the LSP refresh interval.
The seconds parameter enables the router to keep LSPs for the specified length of
time. If the value is higher, the overhead is reduced on slower-speed links.
