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.
