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 specified 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 flooding of
refreshed packets causes.

Syntax

9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
To configure 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.
max-lsp-lifetime
Set the maximum time that link-state packets (LSPs) exist without being refreshed.
Syntax
max-lsp-lifetime seconds
To restore the default time, use the no max-lsp-lifetime command.
Parameters
seconds The maximum lifetime of LSP in seconds. This value must be greater than the
lsp-refresh-interval command. The higher the value the longer the LSPs
are kept. The range is from 1 to 65535. The default is 1200.
Defaults 1200 seconds
