Section13.6.9
Managing the Lifetime of LSPs
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, the maximum time limit is 1200 seconds. However, this interval can be customized for
different routing types within the range of 350 to 65535 seconds if needed.
Th lifetime interval is configurable for each area and routing type in the IS-IS network.
NOTE
For information about configuring the refresh interval for an LSP, refer to Section13.6.10, “Managing
LSP Refresh Intervals”.
