initial_wait_interval seconds second_wait_interval seconds (OPTIONAL) Enter the initial wait time, in seconds, before running the first LSP generation. Range: 0 to 120 seconds Default: 1 second (OPTIONAL) Enter the wait interval, in seconds, between the first and second LSP generation. Range: 0 to 120 seconds Default: 5 seconds Defaults Defaults as above Command Modes ROUTER ISIS Command History Version 8.3.19.0 Version 8.3.12.0 Version 7.5.1.0 Introduced on S4820T Introduced on S4810 Expanded to support LSP Throttling Enhancement Usage Information LSP throttling slows down the frequency at which LSPs are generated during network instability. Even though throttling LSP generations slows down network convergence, no throttling can result in a network not functioning as expected. If network topology is unstable, throttling slows down the scheduling of LSP generations until the topology regains its stability. The first generation is controlled by the initial wait interval and the second generation is controlled by the second wait interval. Each subsequent wait interval is twice as long as the previous one until the wait interval reaches the maximum wait time specified (interval seconds). Once the network calms down and there are no triggers for two times the maximum interval, fast behavior is restored (the initial wait time). lsp-mtu e Set the maximum transmission unit (MTU) of IS-IS link-state packets (LSPs). This command only limits the size of LSPs generated by this router. Syntax lsp-mtu size To return to the default values, enter no lsp-mtu. Parameters size The maximum LSP size, in bytes. Range: 128 to 1497 for non-jumbo mode; 128 to 9195 for jumbo mode. Default: 1497 Defaults 1497 bytes Command Modes ROUTER ISIS Command History Version 8.3.19.0 Version 8.3.12.0 Version 7.5.1.0 Introduced on S4820T Introduced on S4810 Expanded to support LSP Throttling Enhancement Intermediate System to Intermediate System (IS-IS) | 929
