Concept Guide
Parameters
seconds The LSP refresh interval, in seconds. This value has to be less than the seconds value
specied with the max-lsp-lifetime command. The range is from 1 to 65535
seconds. The default is 900.
Defaults 900 seconds
Command Modes ROUTER ISIS
Supported Modes Full–Switch

Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
The refresh interval determines the rate at which route topology information is transmitted preventing the
information from becoming obsolete.
The refresh interval must be less than the LSP lifetime specied with the max-lsp-lifetime command. A low
value reduces the amount of time that undetected link state database corruption can persist at the cost of
increased link utilization. A higher value reduces the link utilization the ooding of refreshed packets causes.
Related Commands max-lsp-lifetime — sets the maximum interval that LSPs persist without being refreshed.

Usage Information To congure the number of area addresses on router, use this command. This value must be consistent with
routers in the same area, otherwise the router forms only Level 2 adjacencies. The value must be same among all
the routers to form Level 1 adjacencies.
