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.
