428 Managing LSP Refresh Intervals
Section 5.18.9
Managing LSP Refresh Intervals
IS-IS retains Link-State Packets (LSP) in the Link-State Database (LSDB) for only a short period of time unless
they are refreshed. By default, LSPs are retained in the LSDB for 1200 seconds (this is referred to as the
lifetime
of the LSP) and are refreshed every 900 seconds.
The refresh interval is configurable for each area and routing type in the IS-IS network.
The following sections describe how to configure and manage refresh intervals for LSPs:

For information about configuring the lifetime of an LSP, refer to Section 5.18.8, “Managing the Lifetime
