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.
