configure isis area timer max-lsp-lifetime

configure isis area area_name timer max-lsp-lifetime seconds


This command configures the LSP lifetime timer for locally originated LSPs.

Syntax Description

area_name Specifies the router process for which you want to configure the LSP lifetime timer.
seconds Specifies the LSP lifetime in seconds. The range is 1 to 65535 seconds.


1200 seconds.

Usage Guidelines

This value should be configured to be greater than the LSP refresh interval, which is set with the configure isis area area_name timer lsp-refresh-intervalseconds command. The remaining lifetime value is included in LSPs when they are flooded. Routers age out LSPs from other routers using the remaining lifetime provided in the LSP. If a refreshed version of the LSP is not received before it is aged out, an SPF recalculation occurs, possibly resulting in routing around the router from which the LSP originated.


The following command configures the LSP lifetime timer for 1800 seconds:

configure isis area areax timer max-lsp-lifetime 1800
