Section13.6.7
Managing LSP Generation
IS-IS generates new Link-State Packets (LSPs) every 30 seconds by default. However, the interval can be
configured anywhere between 1 and 120 seconds.
Since the introduction of a new LSP causes other routers in the area to recalculate routes, it is recommended to
increase the interval to decrease flooding during periods of network instability, so as to reduce the load on other
routers in the area.

Viewing a List of LSP Generation Intervals
To view a list of LSP generation intervals configured for an IS-IS area, type:
show running-config routing isis area name lsp-gen-interval
Where:
• name is the unique name for a routing process that belongs to a specific router.
If intervals have been configured, a table or list similar to the following example appears:
ruggedcom# show running-config routing isis area Area_1 lsp-gen-interval | tab
