lsp-refresh-intervalSet the link state PDU (LSP) refresh interval. LSPs must be refreshed before they expire. When the LSPs arenot refreshed after a refresh interval, they are kept in a database until their max-lsp-lifetime reacheszero and then LSPs is purged.S4810Syntax lsp-refresh-interval secondsTo restore the default refresh interval, use the no lsp-refresh-intervalcommand.Parameters seconds The LSP refresh interval, in seconds. This value has to be lessthan the seconds value specified with the max-lsp-lifetime command. The range is from 1 to 65535 seconds.The default is 900.Defaults 900 secondsCommandModesROUTER ISISCommandHistoryThis guide is platform-specific. For command information about other platforms,refer to the relevant Dell Networking OS Command Line Reference Guide.The following is a list of the Dell Networking OS version history for this command.Version 9.0.2.0 Introduced on the S6000.Version8.3.19.0Introduced on the S4820T.Version8.3.12.0Introduced on the S4810.Version 8.3.11.1 Introduced on the Z9000.Version 7.5.1.0 Added support for LSP Throttling Enhancement.UsageInformationThe refresh interval determines the rate at which route topology information istransmitted 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 linkstate database corruption can persist at the cost of increased link utilization. Ahigher value reduces the link utilization the flooding of refreshed packets causes.RelatedCommandsmax-lsp-lifetime — sets the maximum interval that LSPs persist without beingrefreshed.994 Intermediate System to Intermediate System (IS-IS)
