In order to ensure that the LSPs in the whole area can maintain the synchronization, all
the current LSPs will be transmitted periodically.

Set LSP refresh interval
Restore the default LSP refresh interval
By default, LSP is refreshed every 900 seconds (15 minutes).
5.2.22 Setting Lifetime of LSP
When a router generates the LSP of the system, it will fill in the maximum lifetime of this
LSP. When other routers receive this LSP, its life time will be reduced continuously as
the time goes. If updated LSP has not been received before the old one times out, this
LSP will be deleted from the LSDB.
Perform the following configurations in IS-IS view.

By default, LSP can live for 1200 seconds (20 minutes).
